It may help to reveiw what GMs can, and more importantly, can’t do for players. It can help prevent a lot of frustration.
While bugs are really frustrating, Developers are the ones who fix bugs after QA takes the reports, reviews them, researches them, replicates the bug, etc. In very rare cases the Devs allow a GM to fix a specific thing for players - but most of the time GMs are not given any tools to change the game. Having GMs mucking with the game like that would cause chaos, if you think about it!
