First, this game is great. Good job!
On my latest game though, the game keeps crashing after I build the Pyramids. I thought the problem might be coming from a mod so I restarted a new game without the mod and the same thing happened. After pressing "End Turn" the game says "waiting for other players..." and then closes itself after some time. I'm on Android on the latest version of the game (3.11.13)
I wasn't sure if there was another place to report bugs so I just posted it here.
Cheers!
