Did this happen in the original game?
Don't know, very likely yes.
So this is a well known problem?
No, it's not well known, I hear it for the first time.
But I don't normally camp in the craft
Is it unfixed because 1. it's hard to fix 2. deliberately kept as a vanilla "feature" 3. just haven't gotten around to it yet?
I don't know.
It looks easy to fix, but I never did even a single xcom map in my life, so I can be completely wrong.
From DEV standpoint, it works fine
