Fatal problem.

So i was working on some tiles for my project. kind of screwing up lightly so i'm not like upset over the progress lost but anyhow in the midst of developing it i was turning on and off the grid with CTRL + G. Feature works flawlessly every time. But i accidentally hit CTRL + G + H because my finger slipped and hit H slightly after i hit G. Right after the program minimized into oblivion. It was still active under processes but there was no way to bring it back up, it completely disappeared from all active task bars and stuff and i don't think it minimized anywhere off screen. I tested it and i did CTRL + G and CTRL + H individually and nothing happened. Then i replicated the circumstances and did CTRL + G + H on purpose and i got the same results. I did a quick look to see if this was some feature but i couldn't find anything on it. It's a pretty easy mistake to make if you're not careful since hitting CTRL + G while developing tiles is pretty necessary and you could easily lose all of your progress. Anyway that's the only tile i've noticed. Thank you for reading and i hope this helps.
