so i have tested round_end event and OnMapEnd function.
1.If all players die in one chapter,only round_end will trigger.
2.If players change map in the half of the chapter,only OnMapEnd will trigger.
3.If players finish one chapter,both of these will trigger.
but what about this event: map_transition
it looks like trigger in the end of every chapter,but it seems that incorrectly happen in the last chapter.
Althoght WIKI say that "When campaign cinematics start",i dont know what is the "campaign cinematics".
