**also. when firing a companion, make sure that you do it when your in the location that you recruited them in. this saves them wondering off and getting lost/stuck when walking back to there main location. which seems to be the main reason for them going missing.
*and for more safety, turn off auto-save. doing so speeds up loading times and resolves a few errors involving entering certain areas. this does NOT solve the strip crash problem. but i have a found a solution to avoid it.
the strip issue seems to revolve around the "Debt Collector" mission you get from Freeside. The last part of the mission involves killing Caleb McCaffery and taking his hat as proof. the issue doesn't lie in taking his hat, it's about how you kill him. whatever you do, do NOT shoot him in the head, make sure its still attached when he's dead, then take the hat. i've played this mission on different saves and it seems to crash entering the strip if the hat is still on his head after "taking it off", which only happens if he's decapitated. if his head is still attached, taking his hat removes it from his body out right. thus avoiding the bug.
***another little bit of advice about that quest is if you've already done that and don't want to start over again just because of that quest, and your using the Old Cowboy Hat trick found by other players. whatever you do, do NOT save in the strip, even with the hat on. it totally kills your game and you won't be able to access that save/game at all. thus losing many hours of play and your sanity too. trust me, i had to restart after losing a game with over 50 hours of play to this problem.
**and if your experiencing that bug and walking around the strip after using the Old Cowboy Hat, whatever you do. do NOT take it off, and if you have try not to focus your view in the direction of the body until you've put the hat back on as it can be a problem and freeze your game.
*watch what you pick up too. some quest items have bugs where they cannot be dropped even if the related quest has been completed. Like Motor-Runner's helmet for example. it may be a small problem but if your like me and are a bit of a neat freak and don't like seeing item's in your inventory you don't need yet can't get rid of and a costing your weight etc.. you'll totally understand where i'm coming from and why it's a problem.
*and on the topic of super-long loading times. copy the game to your hard drive... this dramatically cuts the loading times down. also, it seems the longer you play the game in one sitting the longer the loading times seem to take. my advice is to save in a good place *see above* and turn off your xbox for about five minutes or so. then start it up again. this gives the game/console a bit of a rest which it needs from playing such a big game. this will shorten the loading times down once again.
i can understand people's anger on this huge subject but i can also sympathise with bethesda/obsidian in certain aspects of this. these days the gaming market is huge. one of the biggest in the world, maybe even the biggest. they have a lot of competition especially this time of the year coming up to christmas and new years. they have to compete with huge games franchises such as the fable series with fable 3 and star wars with force unleashed two. and other games such as black ops. getting their game out before these gives a huge boost to their sales as not everyone can afford all the games that come out in the holiday season. so many often go for the first big one that comes out. and christmas sales are massively important, especially for games. so things are going to be overlooked whilst trying to get it ready for release. maybe not this many, but it is a huge game with thousands of tiny things going on all the time inside the game. the developers aren't going to catch everything.
that's what we're here for. game developers rely heavily on the players to find the things they miss and have forums like this for people to discuss what they find. therefore helping the developers work on the problems that we have found with their products. they don't need to be scrutinised for the bugs/issues, they need help from us to make their products as perfect as we possibly can. remember, there's a few hundred of them and millions, even billions of us. the faster we work with them the quicker the issues are resolved. so if you find something wrong with new vegas or any game. report it, and make sure it's known of.
***NEW BUG FOUND. this is regarding a smaller bug i've recently found. it's not so much a game destroying one but it can ruin the overall game experience. this involves the quest chains "The House Always Wins" for mr.house and "Wild Card" for yes man. if your are planning to side with yes man but are perusing it through mr.house's quest line (both ask you to do the same things). i've discovered that if you decide to kill mr.house after visiting the el dorado substation for him, then inform yes man. a bug occurs after yes man takes over the lucky 38. after talking to him on mr house's monitor you will be unable to switch back to 3rd person mode for the rest of the game. i'm not sure what causes it. but killing mr. house before visiting the substation and then going there for yes man instead seems to solve this problem. i know it's not a MAJOR issue, but for me personally, not being able to use 3rd person takes a lot from the game play.
ill update this if i find any other ways of avoiding certain bugs when i find them.
thanks
