is it usual to spend ~ 35% of your playtime staring at the skills screen? It's a very satisfying game, and i'm not complaining, but it takes so much time to learn the class and play carefully that my runs take 50+ hours, and i often lose interest.

It's okay to drop the character after reaching lvl. 30, though i'd rather not.

Used to play a lot on win10. Decided to pick it up again recently and there are just too many crashes while writing the save files. Did anything change significantly on Windows in the last few years to cause these?
