8 years ago Probably because we don't de register our observer on destroy of an activity. Which we should do. On Mar 21, 2016 3:29 PM, "0x4849a" notifications@github.com wrote:

Short version : After pressing the save button in Edit Game, it's crashing here on Homefragment.update() which calls observer.update(this) in Observable which calls thing.update(), etc.
Also, if you press back at any point to get to the login screen, your future bids won't save. It doesn't matter if you change users, these problems will probably persist regardless. I am guessing these are some of the bugs we experienced in the lab but we weren't aware of it at the time.
I rolled back my source files to before I was using serializable, and it doesn't seem to have anything to do with that since that crash still happens before it was being used.
