I have officially reported this bug before, but it was rejected because it could not be reproduced. Understandable, since it is very hard to reproduce since it happens quite randomly.
I am raising this topic to see if anyone else has gotten work lost due to built-in pixel graphics editor losing progress. And perhaps find out what causes this, is it just me, construct or browser buggy.
Basically I just lost an hour of progress because I forgot to close the pixel editor and re-open it. If there was a save button only... the one that saves current edited image in a project while pixel editor is open, not into separate file.
* My C3 window with one project has been open 3 days now.
* I have several frames, I was working with one of them.
* After about an hour, the frame reverted back to its initial state, I lost all progress as I was drawing.
* This happens when I have used the selection tool and moved stuff around with it. It reverts to pre-selected position in random times later, losing all the changes in between (pencilings, fillings, etc).
* My browser is Microsoft Edge, but this was also happening in Chrome. Construct is open separately, not in my main browser window.
My guess is that some cache somewhere is getting full and it is reverting to some initial state. But sometimes it happens quite quickly. I would prefer if I lost undo states instead of progress...
Is there something I can do to prevent such loss of data?
Maybe this is also help, although I don't know what time the errors happened or if they are correlated to problem atl all:
