ToME: the Tales of Maj'Eyal

My berserker learned Ice Storm from a Tome of Uttercold. Sometimes using it causes several Lua errors to appear. It usually happens when fighting groups of enemies: the Prides, orc patrols, and the final battle.

Have you used the in-game bug report to submit the stacktrace? If not, can you please look in your game log (a text file in the ToME4 directory), search for "Lua error" and past the stacktrace here?

I sent an in-game report a few times, but I had to shut the game down whenever it happened. Do the bug reports still reach the developer?
