For the two Pelican bugs, it's not really a bug from what I understand. If the pelican gets lightly damaged by stratagems, it will leave with only one player. If it gets heavily damaged, if will start burning and then you might as well call a 380 on the team (unless there's a kill major order)
Except it makes no sense as a gameplay mechanic at all, isn't explained anywhere and fucks over people who are supposed to work as a team by getting rid of the samples.
It's 100% a bug. If it isn't, then it's a reaaally stupid decision that should immediately be reversed.
He's saying there could be a hidden mechanic behind it, while I agree with you that it's annoying af, it could be a fun added urgency. If it didn't appear so much like a bug, and the game actually made you aware thats what it was trying to do.
