Rollback on ground and the caves causes the game to crash! Porting to wormhole causes the game to crash! Once the game crash, it takes forever to get back to the game.. it keeps crashing over and over and over again till I finally get back to the game and it takes forever to load. This ONLY happens in my MAIN world, the other ones that I've made runs smoothly with ZERO crashes and it doesn't take FOREVER to load.
Save files via Dropbox and one I upload: https://www.dropbox.com/s/j6tliv34bzdng20/PS4.zip?dl=0 both are recent saves.
When I try to invite friends, they get this error: http://imgur.com/kGUt3IE It only happens with my main world, they are able to get into my other servers/world.
