When building with t2 fabbers and t1 together they bug out and don't build mass energy or metal its really annoying when u think u have que them n have to keep coming bk n giving separate orders if this has been posted already my apologies Ive been away for a bit
Yes, I've noticed that too. It happens, because those nasty little T1 bastards stop in front of the T2 guys, and they get stuck behind them, trying to figure out how to get to the other side, but they can't. It's an issue with their pathfinding. Needs to be fixed, fo' sure!
Metabolical noticed this, too, when he was streaming. So there is no doubt they are aware about it and will fix it. Meanwhile as a workaround, assign the T1's to assist the T2, instead of selecting them all and giving them the order. Yes, not really satisfying. But better than having to babysit the fabbers all the time.
