Also glitches if there is along delay between last grenade throw and detonation. It comes up with the back/reset overlay but underneath is the Clear-> success button.
Bad bugs:
1. Staff don't go to floor they are set for.
2. Can't drag elevator to basement.
3. Can't click people or objects during pause.
4. Too hard to click people even at 1x.
Hm, guess you are right
