I had made an extremely simple project outlining some features to expect in my latest project in the online editor. It worked perfectly for at least two days, then all the images disappeared. The costumes, sprites and scripts were all still there, but the costumes were blank; and were described underneath them as 0x0.
This cannot be due to me not saving properly, as all the sprites and costumes were still there, but blank.
Any way to get back my images, or any known glitch that could have caused this?

I don't see any 0x0 costumes in that project.

That's really weird, everything's back now…
