I saved my work, and a bit later I wanted to return to that save which was my best save. The save was listed on the "Local Solutions" screen, but when I tried to load it, loaded a completely different save. I did this 3 or four times and on the final attempt the save was no longer even listed in the save box. I know I might have clicked delete in frustration on the last attempt but given the strange behavior of loading incorrectly, it's not unresonable to assume that there is a bug here.

Unfortunately, I had to sign off so I lost the log.
