The only bug I had was the first time I went back to the spaceship/RV, I saved and then couldn't leave the spaceship. I had to close and re-open from the save. I have not been able to recreate it, though. Other than that, I noticed a lot more slowdown and stuttering the longer I was in the game.
---UPDATE---
After reading your devlog, I may have had the crank out. Just noticed the staircase disappears when the crank is out. Nice touch!
