ToME: the Tales of Maj'Eyal

Whenever I play an Adventurer, and open the talent trees page to level up, the game freezes, and sometimes either gives me an error message (Which I have sent), or even crashes the game.
I'm not sure if this is due to there being too many talents appearing, as I do use a lot of different mods at once, yet cannot track the bug down to any specific one.

Do you have lots of addon races installed? If so, I wonder if having too many talent categories is the problem. Try deactivating the addon races you're not using and see if that fixes the problem.

Apart from that, I can't offer much advice without seeing a detailed error message. It's normal that you'll get some lag when opening the levelup screen as Adventurer since it loads lots of categories, but I've never had it crash.
