Cannot revive teammate when killed on a platform that was destroyed

I’ve had this happen twice now on XBox One. It makes me weary of trying Iron Mutant mode lest I have this unlucky thing happen and lose a character.

First time was the Metal Fields, Farrow was killed while on top of a train that exploded. I was unable to select her with another character to revive her.

This time in The Unenlightened, the MIMIR Z600 blew up a whole house Magnus was perched in and once again I cannot select him to revive him.

I would upload a screenshot but the site won’t let me.

PS Thanks for all your hard work, I’ve been enjoying this game immensely! With the new XBox update I’ve already noticed changes that make me excited to keep playing.
