Fixes a server crash in No More Room in Hell 1.11.4, seen as:
- server.dll + 0x2ff6a1 on Windows
- server_srv.so!CNMRiH_WeaponBase::DoShove() + 0x52f on Linux
You'll see this crash occur when a zombie grabs a player and gets killed unnaturally (via "Kill" input or similar). An example of this would be nmo_lighthouse_v2 when a player gets grabbed as they finish barricading the town doors.
The fix will also let the player walk again after the fact.
