## About The Pull Request
For a moment, I had forgot about saying I'd take a look into it, but it
seems the new fix to hard dels is causing some runtimes with empty
weakrefs. Beside, WEAKREF() doesn't work well with qdeleting atoms (so
you'd have to access the weak_reference var directly).
How immersion works is quite confusing even for me who coded it, trying
to work around some of the hefty limitations of the engine truly blows.
I could even ask MrMelbert to make a proc-chain chart for it.
But yeah, long story short, I only have a bare idea where the uncleared
refs would be. I suspect it could be `immersed_movables`. It's totally
possible since the proc can early return in a few cases, thus skipping
the ref removal, hence the title.
## Why It's Good For The Game
I didn't like the PR that implemented weakref usage into the element,
but I let it pass because "hard dels = bad". However, the runtimes
aren't that much more pleasant either.
