(I know this is a pretty old forum, but it seems to be the only place where I can get help with this problem)
I've been having a problem with any RA2 mod I install (DSL, any of the Beetle Bros', etc.). It's really difficult to attach parts to other parts, specifically attaching extenders/attaching things to extenders. I have to align it up, to the pixel, in order to attach them. This makes robot building pretty much impossible, except for in the base game. Can someone help me with this?
