Summary0005157: Random collisions force player to drop held item
DescriptionReported 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 ReproduceBoot 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.
TagsNo tags attached.

Here is stack trace which forces the drops:

Looking into idEntity::CheckCollision, I see:
+ this 0x00000290d84de964 Entity "func_static_1872": num=2131 def=45 idEntity * {idStaticEntity}
+ collidedWith 0x00000290d847e014 Entity "mill_cityguard_1": num=1929 def=173 idEntity * {idAI}

+ [0] 0x00000290d84de964 Entity "func_static_1872": num=2131 def=45 idEntity * {idStaticEntity}
+ [1] 0x00000290d82ec354 Entity "atdm_handle_curved_rotate_double_right_1": num=2145 def=1747 idEntity * {CFrobDoorHandle}
The drop happens on the last StopDrag call.

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