Mimicreeps jump out (and die) of Backup Chassis hand (while possesed atrium is inserted)

I was using a mimic as a Lazy explorer on my main chassis, when I then remotely changed to a different chassis it left the main chassis hand after returning, and then it immediately died.

I'm assuming this isn't the intended interaction with how the mimics leaving P. shadow atrium WXs when moving to the caves was fixed, however if it is intentional that a mimic will leave the chassis hand slot if they are unoccupied for long times, then I'd ask for that to be changed, as it makes using multiple bodies with P. shadow atriums annoying.

Chassis not being able to even keep a single mimic in their active hand slot makes the bonus of using mimics null when you constantly swap chassis, so I hope it's either fixed, or changed if intentional, thanks!
