gzdoom-gles/src/dobject.cpp
Christoph Oelckers 87484950cf - removed an assert from APowerMorph::EndEffect. With some recent changes to DestroyAllInventory it appears that the asserted condition no longer is true at this point when ending a game.
- fixed: When replacing a tentative class, the pointers in the morph objects were not replaced. Instead of adding more ReplaceClassRef methods I chose to integrate this part into the PointerSubstitution mechanism and delete ReplaceClassRef entirely. The code had some oversights anyway that would have caused problems, now that non-actors can be created.
