Bug: delayed/game crash between rounds

Summary

once a round is completed the game goes into to a black screen for the game to load, usually this takes around 10sec which is reasonable. in my case there waiting around a minute before they get to play to the next round and sometimes it crashes some peoples game. i fixed the issues before because a barrier was colliding with vehicle but then after that it started to happen again. Help on this as this is a huge issue which needs to be fixed (ive asked a lot off people before submitted this report)
