[V18.51 HF3 - Geoscape] Injured Soldiers Assigned to Dropship

Following a rather buggy base defense (I will post the bug report for that soon), I immediately had to redeploy for a terror mission - only problem is 5/8 of my slots on my dropship (the first one) were unusable - five soldiers had been assigned to it during the base defense, were injured (such that their name is now in red). As they are "assigned" to resting, I can't unassign them from Charlie-1, but nor can I assign anyone else to it. It's a bit game breaking.

I've had injuries before, and never had this happen. I suspect it's something to do with being injured -during- a base defense.

I have saves before the landing and a couple during the defense itself, if that would prove useful in troubleshooting/recreating.
