Hey there, thanks for the bug report. Yeah, we've been able to verify the crash happening from the game locking up on enemy turn. We'll get this one fixed asap
For the saves being made even though the feature is disabled, this setting is overridden when playing on an experimental build, due to the nature of it being rather unstable, we've made it so that the game overrides the save settings in case crashes happen (like this one)
For the save file being on one drive, I'll have to ask the team a bit on this one
