So @grazer asked is a previous discussion that I make my own thread about this issue, so here I am.
Every now and then, the browser freezes for a few short seconds, and then blinks and goes back to normal. This happens at least 5 times every time I open the browser. While this isn’t much of a big deal on other websites, here on Flowlab, the game crashes and any edits made to the game are erased. If you quickly press “OK” before the crash finishes in the behavior editor, the behaviors will be saved. However, if you were to repeat this step in the sprite editor, EVERYTHING within the sprite art (animations, colors, even the sprite itself) will turn into a mess of pixels and glitches. Instead, you would have to not press OK at all in the sprite editor when the crash happens. You’ll lose your past progress, but at least your sprite as a whole is preserved.
A while ago, I decided to open the console log after this glitch/bug happened and I found this warning:
Apparently, something happened that caused the website to lose some data considering a game and it just crashed in the process.
I mentioned earlier that this bug happens at least 5 times before stopping, and when that happens, a few random things happen:
- In the first, second, and fourth crash, the website just returns to normal, but all unsaved progress is lost.
- In the third crash, all forms of texts, like labels and alerts, lose their color, and all unsaved progress is lost.
- In the fifth crash, the games start running half as fast as they used to, even in the editor. All texts appear to be glitched out, and all unsaved progress is lost. The crashing stops universally, but the game acts like it is “broken”.
This bug has been happening to me for at least a year, but only now am I reporting it because of the following reasons:
- I originally thought that this problem was exclusive to me since I made past attempts to tell other people, and even though they did help a bit, it did not solve the problem. Now I see that a similar progress loss issue is happening to @Ramshacklegamestudios and @GrimProductionZ.
- This context loss issue happens regardless of what website or browser I am using, so once again I thought that it was exclusive to me. While other websites suffer no problem from this “crash”, for Flowlab, results can be catastrophic for my patience, which is normally very strong.
I hope that somebody can tell me what the problem seems to be here, and hopefully we can find a fix to this crash. 
(Just to re-tag @grazer one more time)
