Have you F2’d them? (It’s starting to look a bit like whack-a-mole - they get one set of floating objects back on the ground, more immediately pop up…)
Working on compiling a gallery of them at present. There are a lot. I’m guessing there’s a tech-debt related cause behind this (fix one problem, 23 more problems are exposed in the spaghetti.)
I assume you know how to get teleport coordinates for locations? (alt-shift-L, then ctrl-c to copy to clipboard (then alt-shift-L again to turn back off))
