update_zombie_pos: wanted to move the blob to 86,89,0, but new location already has the small blob

[TempestMaiden]

Describe the bug

I'm getting a spammy error message in my most recent game, looks like something similar to a bug that was fixed before the 0.E release:

DEBUG : update_zombie_pos: wanted to move the blob to 86,89,0, but new location already has the small blob

FUNCTION : bool Creature_tracker::update_pos(const monster&, const tripoint&)
FILE : src/creature_tracker.cpp
LINE : 127

I've gotten a related error once on load involving two blobs occupying the same space.

It's not a crash or anything, the "continue" option has worked just fine every time it's popped up so far, but it's happening often enough to be annoying.

It may be related to my leading a security zombie into a blob trap and shutting the door behind me.

Steps To Reproduce

Not sure what's causing the error, so I've no idea how to reproduce it in a new game.

Expected behavior

Gameplay shouldn't be regularly interrupted by an error message.

Sounds like #37683 again, which was resolved by #38497, but perhaps this example has a different root cause.
