Um..Viion have you ever made something that is complex? I mean you get RPG Maker VX for 50 bucks go into the coding area, delete a line of code, leave it alone for a couple weeks then come back and try to find the mistake and fix it. When you fix it you will probably find there is still an error, you have to go and search through thousands of lines of code because when there is an error it just doesn't work, its not like Windows is going to pinpoint the problem for you (because the core coding that makes everything work is messed up)

I hope that makes sense, maybe it doesnt though, but that is why they HAVE to run all the checks that were listed and YES ALL THAT IS PART OF MAKING AUTO ATTACK. Its not just slapping in a system and calling it a day.
