So yesterday I was finishing up my map with spawn points and other finishing touches when my game crashed. I loaded up the game again and tried to edit my map only to find that my monitor is trapped outside of the map and unable to access the Forge menu. This is extremely frustrating as I have put 8+ hours in this map and the fact that my map is basically unusable even in customs is quite upsetting. Please 343 fix this!!!
Try inviting another player and see if they spawn correctly. They can then delete some objects to reduce the chance of this problem.
