So I started to test the new beta version today, and the game crashes randomly in particular cases. At my first playthrough, I tried both the magic and the adventuring trees yet no crash happened. After a few hours I started a game with only researching Adventuring, and the game keeps crashing constantly (goes black, and then eliminates). 

The first time it crashed, i was casting a Production spell on my town. Loading and doing the same, had the same result. When I tried casting a different spell (familiar), the game crashed as well.

I did a different action then a spell, and only afterwards casted it, and it didn't crash, YET, it crashed in several other occasions: A random move turn, going inside an Inn and visiting ruins.
