Hm, unfortunately I can't repeat it with this save, either! (Also I edited to thread title to add that this is specifically the latest version and playing under Polymind mode.)
I did hear from Azken mentioning that they crashed while releasing control of a bot once, though that was an automatic release due to losing their last Recycler parts to a Crusher. So I tested that scenario a lot and couldn't get it to repeat, either...
Apparently there's something going on with releasing control in rare cases, although interestingly Azken had a crash log, one that manually crashed due to detecting an invalid situation of the kind that should be fixed before release but I never actually had it happen, so there was nothing to fix at the time...
Seems somewhat different from yours here, if it's possible for you to repeat it that easily. I will try a few more tests to see if I can get it to happen. So far I've tried many dozens of times using various methods and it's all working normally :/
