Hi ,I got 2 things here to ask you all.

1st question....

When you go to Sloan early in the game and they stop you saying deathclaws all over the place and you take the quest to clear out Quarry Junction and you do it later because you'd be crazy to early in the game hehehe!!!

Anyway many levels later and with better weapions than a varmint rifle you go and clear out Quarry Junction and when you go to that little cave down in the quarry where the deathclaw eges are even thou you killed all the deathclaws one deathclaw seems to pop up out of nowhere and its done this evert time I've played the game.... do you get that pop up out of nowhere deathclaw too?

The 2nd queation ....

When you go back to Sloan and tell them Quarry Junction is clear now, he says "great now we cal go back to work"

But the workers never go back to work at Quarry Junction. But if you go to Boulder City early in the game giving the quest to go their you will see their are no works in Boulder City ,but after clearing out Quarry Junction their will now be workers in the Big Horn Saloon in Boulder City. Why dose that happen strange.

1 where does this Deathclaw specifically pop out from? You might not suspect it.

2. Those workers probably worked at Boulder City before the limestone stopped coming in. Now, after some 'badass' cleared it, they heard word of this feat, and strolled back to one of the last standing buildings to wait for the supply of limestone to build and get to work.
