Okay, not sure if any of these ideas have been said before. If they have have been said, then great minds think alike. Also not sure if I can submit two ideas, of not just take the first one out of the two, anyway here they are(Keep in mind I played this game 1 time and died off spawn GG to me XD) :
Idea 1: When the hourly disaster comes for that section you get hit with nausea and blindness (possibly slowness as well). Also I think it would be fair to get a compass that directs you to spawn in your inventory that points you to spawn so you don't get lost
.
Idea 2: A huge flood that comes, it would wash you to spawn and maybe add some skeletons in to shoot you on your way to the middle
