Had it with various Hats and shorts, common issue is when the clothing is on a raised platform, such as a chair or cupboard top, but ive had it on the floor as well as well

i have encountered this as well, the only common theme i can find between items ive found that cannot be picked up is that they where all camouflaged clothing. hats and pants specifically. never had that issue with a pair of boots tho

still a few items are floating especially in back room of hotel gostenetsa) but looks stable now, will report specifics later
