Alright. I finally finish modding my game up with 142 mods, from start to finish. LOOT says there are no dirty plugins, no warnings, or any errors.

I start up my game with SKSE version 1.7.1, the stable build. Race menu tells me that it was expecting the beta build, 1.7.2 or higher. SKSE silverlock shows only 1.7.1 or 1.7.2, nothing higher.

So the game starts as normal, besides the whole race menu telling me it expects me to have the beta build of SKSE. nothing is going wrong as olfric stars into my soul, judgingly....

I decide, what could hurt? i exit the game, and update SKSE to the Beta build. i follow GOpher's steps to the letter, move and replace, and data folder from archive mod. after i update SKSE, i start the game.

i start the game.. in the air... spinning around like a madman as the carriage freaks the heck out! Here's my steam screenshots, they are the newest 2: http://steamcommunity.com/profiles/76561198091207900/screenshots/#scrollTop=0

WTF mate?

Are you starting Skyrim through skse_loader and not through Steam by clicking play in the client?

i may be an idiot, seen plainly by my previous 2 failures to launch the game before i asked about this bug. Since my Steam app and client runs as Admin, i need SKSE loader to also run as Admin in order to overwrite the standard launcher. this has been fixed, im running through SKSE launcher, not steam launcher. (the second failure wa sa mod conflict i fixed. i had gotten rid of something that was a master for another mod. but it's fixed now)

There is no problems other than SKSE's version being different.

This is unlikely to be related to SKSE. More likely to be from a mod or an ini tweak.

For instance, Helgen Reborn used to recommend that users not install until after they completed that first sequence. I don't know if this is still the case.

In any case, the cart bug you report is not unheard of, even in vanilla Skyrim. One way to get around would be to use something like alternate start--Live Another Life.

i never encountered this bug after 20 character restarts (due to mod failures had to always restart) till now. so yeah.... but i understand.

the first time this happened i took screenshots. the second time i loaded skyrim up. it was much closer to the ground. the third time was the charm, it started evenly, and we got to helgen. seems it just is a freakout bug for skyrim period you need to load past.

Does framerate exceed 60? This could be a simple physics bug due to too high framerate.
