[Crash] Lots of voxel deformation causes crashes to players loading in

When loading in an area with lots of Voxel deformation/changes in multiplayer the game may crash when loading in that area. (see attached crash log). This occurred multiple times when both travelling to the area ingame, aswell as when trying to rejoin after the crash. After more than a few attempts we were able to log in again after which the game ran ok. It also seems that keen official server admins are aware of the issue so they may be contacted for more information aswell.

After diving into it a little bit myself it seems to be caused by the game streaming in the voxels slower than the thread which generates the physics for them processes them causing keynotfound exceptions.

STRP:

1. on a multiplayer server

2. make an area with a ton of voxel deformation

3. travel to that area from a spot where that would not be loaded before travelling (do this at the same time with multiple clients to increase the chance of it happening)

4. observe possible crash

This crash does not happen all the time however does seem to have a fairly high rate of occurring dependent on the amount of voxel damage. Multiple clients at once seems to increase the chances of the crash happening too.
