strange pen brush behaviour

Hi, another cause of app strange behaviour. I used mostly pen and get color brush on the sprite sheet. And sometimes copy-paste of the sprite to another cell. So no selection. Then i switched to the map tool. And after a while of working switching to sprite editation and map editation i encountered that while drawing with the pen tool in map it puts a 8x8 square of sprites and it is empty.

I understand that the hallowen is here but this sounds more like a ghost story. :D After restarting it works. So perhaps some flags while switching tabs misplace numbers?

That is all about the problem. Bye.
