qzdoom/src/p_saveg.cpp
Randy Heit 87d7b3601a - Added a check to G_DoSaveGame() to prevent saving when you're not actually
in a level.
- Fixed: Serialized player data must always be loaded, even if it's simply to
  be discarded, so that anything serialized after the players will load from
  the correct position in the file when revisiting a hub map.
