Pretty simple, extremely annoying, happens with almost certainty. Any time you grab a group of 1 or maybe 2 t2 ground engineers with a group of T1 fabbers and give them a build queue to expand on mexs or build t2 energy, they'll do maybe the first one or two and then end up jammed up. The problem seems to be that the t1 bots get in the way of the t2 bots, preventing them from getting within range to start the t2 building. This is incredibly annoying and game destroying - often you'll set up a large eco build queue only to find it's been jammed up and you are in eco freefall. And it happens multiple times per game. If the t1 bots could spread out a bit more or just always make room for the t2 bots, or perhaps if build distance was bumped, this should be fixed. Temporary work around is to use masses of t2 bots only, or air fabbers to assist. My system: OSX Mavericks edit: have been getting this bug on all gamma builds through to 62443
I think the t2 engineers used to be able to bump them out of the way but there seems to be additional pathing issues where t2 engineers just get stuck on buildings rather than going around. At the moment I now use only t2 engineers to build t2 eco because you get much less problems.
