Hey Melchior, new version looks good, but I did notice a few issues when looking around. Apparently the sand texture used on the hourglass in Common House 03 has a bug with it, I haven't been able to figure it out on my end, so I'd just recommend deleting the hourglass on the second floor desk. Also, the trapdoors in the Merchant Hall wings aren't connected, they're supposed to connect the basement levels to the towers above them.
A few other bugs I noticed:


It seems the Imperial walls here aren't connected to anything.

And there's some Z-fighting I noticed right here along the wall with that building sticking out.
Anyway, just thought I'd point out those issues.
