I'm not sure if it's just me, but i crash. a LOT in Axu, which sucks because i really love the game!It's nearly impossible for me to even go through the world map much less be immersed in it, I'm not quite sure what it is but I personally think it has something to do with the rain. I don't think i've ever crashed in the caves, I'm on MacOs, if that's any help

I crash randomly when attacking, i just save before every fight and hope for the best. 

I'm still working on some of the crashes, but am not able to catch every one, since I'm unable to replicate quite a few of them. There were some issues with combat, and saves getting increasingly buggy as you continue through the game. I haven't had a crash in a long time, and mostly see it on OSX and Linux, which I am not able to test on at all. I think the current experimental has the attached debug log, so look into that if you're interested.
