Just before the last drop off point to get into the finale event arena if you dont rush into the area because of something like a trial chest then players/bots will respawn after the finale event if more than 1 of them dies, this happens before you have even jumped down to start the finale event.
I have been in situations many times where i either had no help at all for the entire finale event or only had 1-2 players/bots helping because of how buggy that part of the map is with respawn locations.
