Don't think it's a bug per se, but for some reason C2 didn't save a few hours worth of coding today. No crashes, no errors, hit the save button after coding every new function, closed C2 at some point and reopened it only to find the project in the same exact state it was in this morning when I first opened it. I'm sure it's the same file and everything. Didn't have any backups saved, unfortunately, though I'm not entirely sure it would've helped since basically the save function didn't seem to be working (looks to be working a-okay now).
Really weird. Any clue what might've happened and if there's some way to recover it? Luckily most of the work was simply me experimenting with behaviors and learning stuff so it's not such a big deal if it's gone.
