I just fired this up for the first time on Steam and I'm having some problems with the 360 controller. It works fine up until I either pause or go to the inventory screen. After that all the controls stop working except the right stick. I can save and continue to get everything working again, but every time it does the exact same thing. I'm using the wireless 360 controller with one of those official wireless PC adapters. Google isn't helping. Any ideas?
