If I had to take a guess - with absolutely no experience regarding how the game might work but access to a lot of robots to observe - I think it might be in some way related to the robot not being applicable for the game's spinner mechanics.
Okay... Update: I'm trying it again, and this time the game is staying solid, I haven't had even one crash today.
Hmm. Any ideas what might be different?
No idea at all, but these past three days I've continued to have no problems with it.
