Summary	0005157: Random collisions force player to drop held item
Description	Reported on forums here: https://forums.thedarkmod.com/index.php?/topic/20254-object-manipulation-issue-in-crucible-of-omens/&tab=comments#comment-443685 Basically, after some gameplay on Behind Closed Doors FM the player cannot hold/manipulate any item. It gets auto-dropped half-a-second after player takes it. The issue persists in a save file, but disappears after mission restart. Initially I thought that the objects somehow got into the floor under them, but it is not the problem.
Steps To Reproduce	Boot TDM 2.07 hotfix, and load the attached save on Behind Closed Doors FM. Try to lift chair or candle: they are dropped very fast, you cannot move them normally.
Tags	No tags attached.

Apparently, the code here is wrong, since it does not take entHeld into account at all.
