I played for several hours yesterday, and had no issues with crashing at all. They released a patch since you made this comment that fixed several crashes, so I guess you found at least some of the causes stated in the patchnotes.
The biggest issues I encountered were a problem with selecting submodules of a storage while editing the storage, and a lack of explenation on what watchman actually do other than stand there and look pretty.
Played this from the day it came out in early access. Went off it because reasons. Had a quick look just now and oh my God... It's a completely different game and it looks awesome. Had to stop playing so I can block out some proper time to dive into into. Honestly it just looks so good... :)
