Hello Naufr4g0 👋
It's actually an unfortunate effect of missing bit in the persisted editor state in your browser.
I've noticed that I didn't read the multicolour bit properly when reading the tile data from the memory, now it's been corrected but the incorrectly read graphics data is already saved in the editor session.
If you don't have any changes in the levels, the easiest way to fix this state is to load the prg/d64 again - this will re-read the tiles and the issue should be corrected.
If you have the changes you don't want to lose, export them to JSON file and send the file over to hitori@duck.com, I'll correct it (multicolor flags must be set) and I'll send back the corrected file.
Sorry for inconvenience, I was just too lazy to write the data migration code after the colours bugfix.
