I can confirm. Some weeks ago I could compile it and play with the germans. I don't know the date or build nr though anymore.

I tested it on my own builds when developing obviously and nothing was wrong. Something must have gone wrong since then. I haven't downloaded the build since i've been very busy. K i can disable those in order to prevent weirdness/unforeseen bugs. 

Alright thanks, I will make a new UV2 and bake asap. Is there a deadline for the release already?

No, same reason as @ffm2, and no entity get spawned. Just test it lol. Random guess would be that the Carth stone tech get applied to all civs in p1. But you couldn't train females from them afterward iirc. It seemed a bit odd. Other proprieties of houses are likely to be applied to the wagon that might cause game-play weirdness.

is that because of points 2 and 3? Or a different reason? Not sure how that happened, its not supposed to be like that. That is intentional, as the tech turns them into 5 pop houses.
