when you quickly try to build something it only registers the build hotkey but not the actual building u wanna build , few ppl i talked to have this same issue

some other issues i noticed recently :
voobly forces your mouse to the game room when game launches (can this be turned off ffs?)
launch crashes/freezes when you click your mouse at the same moment your game launches

Install and use Userpatch 1.5 to get rid of the hotkey problem.

and launch in window mod
