Known Bugs              : Due to inability to test with the original DOS
                          EXE of CoD there might be some differences how
                          some of the new DECORATE items behave
                        : The conveyor with burning barrels in MAP01 will
                          desync after some time and push the barrels off.
                        : Unless you set the 'infinitely tall actors'
                          compatibility option the Cyberdemons in MAP10 won't
                          get killed. This doesn't affect playability though.
