Transfer Troops ability can damage your own ship

Not sure if this is intentional, but if you go past the troop thresholds, you might end up damaging your own ship. I just blew my own reactor from a troop transfer. I don't think the crit damage on troop threshold change should apply to own transfers, but rather be queued to happen next time the enemy kills a troop on the same ship.

When you have only one troop left in the current layer, the troop transfer should just be greyed out until this particuler condition changes in one direction or another. Problem solved.
