Yes I get crashs also.
Notice its when bot is ID'ing on sale run.
Or the inactivity. Other times I have no clue.
In way once a day thing dont bother me. But when read logs and it was 1 hr after left. So knowing went 7 more hrs doing nothing... kinda sux.
Only thing I see helps is using least amount of plugins as possible. Just giles.
Raise up stash points some. Not sure if valid, but notice when mostly vendors, less stashing. Was a crash free night.
Make sure use good solid profiles. At start should be few safety type lines of code. To cover deaths, stutters, and weird mishaps.
