I'm tempted to say this bug cost me the game - it at least would have given me a realistic chance to survive the snipe or get a draw.
Fast forward this replay to 13:30 and focus on the red base with the shift key held down and watch my engy do... something. Other than build the pgen and shield that would have given my ACU important extra HP and kept my radar functioning. Sliding doors moment as far as that game goes, but more importantly a completely retarded bug.
