Windows 8 64bit, MG 3.8.0 Beta1.
I was playing tech from Megapack and I had a group of various infantry selected(which I had added to a group with Ctrl+1) and I told them to attack and they didn't. I tried to move them and every time I right-clicked the screen for them to move somewhere it glitched very fast, almost not noticable. I right clicked all over the screen waiting for something to happen and it froze and crashed.
Idk if this was graphics card related, if so my graphics card is the AMD Radeon HD 7970m.
