Known Issues: Updated August 6, 2015

That's the catch, though.

Bugs discovered in Tespia still need (Korean) developer attention to fix. And if you want them fixed before the version goes live, that means immediate high-priority developer attention. GMS just doesn't get that for anything but game-breaking bugs, regardless of where they were discovered.

Thats quite interesting, I didn't know they needed that kind of dev attention to fix bugs, thats a REALLY bad way of doing things if you ask me. I can understand needing developer attention to do major things like request gameplay changes or such (I believe waltzing wanted to see if we could have bosses changed to fit the GMS community more, no news on that currently though) but needing developer attention just to fix bugs is a really convoluted way of doing things, that probably slows down the process alot.
