I have been playing a few ranked games recently and I have found out that some move/build orders would simply "cancel themselves out", while all the action is going on on the battlefield...
It can be pretty disastrous by the time you realize what has been going on, like T1 power generators not building, engineers stop moving/working with all the build orders gone, units not moving as intended, or an ACU not moving to a certain place where you have wanted it to go to?
This is similar to a "ctrl-shift right click" but that is not the case here.
Does anybody have this problem too?
