I couldnt build that fusion there because it seems like there was some unit on that spot, but there wasnt anything!
And no, there was not any cloaked unit there.
Ive seen this kind things happening before, i think its the nanotowers? Ive noticed few times how my krogs cant walk out of the alley covered with nanotowers, while theres nothing on front of that krog, it just wont move over that specific spot, not even in FPS view mode.
So, i think this isnt bug because of new spring release... seen it happening before.
