For awhile I have noticed a problem with the hidden spawn points bungie put into sandbox. They are the places you spawn when there is no spawn points on the map. Anyway onto the problem. I have made a couple of maps on sandbox. 2 of them have had this problem. Okay when you start a custom game round 1 works fine. Then on the second round and beyond they spawn on those spots. When I have a map on the sky box it makes them spawn on the ground floor. I have checked for all starting points in all gametypes but there are none. some of my maps this happens and some of them not. The only solution I found was to put boxes over these "secret spawn points" which work but that means I lose 6 items and when you want every item you can get it does not help. Any solutions?
The only other solution is to put spawn areas with high weightings (low numbers). Unfortunately those spawn points are set into the map incase you canvas the map, without those you would end up in permanent black screen.
I don't see why this would happen. Any placed spawn points should be prioritised over map deafault ones. Are you sure you have enough spawn points? This is unlikely but if 16 players died at the same time there would have to be 16 spawn points to cater for them. If there isn't a spawn point for a player they will spawn on a default point. Also what gametype are your maps using?
I have been using infection and one other (can't remember). I know I have plenty of spawn points. It is set up for 16 people and I was playing with players 2-4 to test it.
