When you want to transfer aliens from one base to another (which has a containment unit), it looks like the capacity of the destination base (right column) is wrong: dead aliens are counted as alive , and live aliens are counted as dead ones.

In my case, I experience this because I have only one Containment in one base only. Perhaps this bug is not systematic, and is linked to the fake Containment workaround when a team bring living aliens back from a mission. I don't know.

<strike>Also, I experienced this for Ortnoks.</strike> (Species is not relevant)

Note that the display in the left column (base of origin) seems correct, because transferring 2 dead Ortnoks really adds to the number of dead Ortnoks in the destination base.
