Not sure I found anything similar to this. (Correct me if duplicate)
So anyway…
In the Skywars game, in the map “Ivory,” the playable area zone is high. After a fight, sometimes I would go into down the stairs on the starter islands to get some redstone, but the “Return to the playable area” occurs, draining my health. The message occurs when you go down the one block on the second stair down.
My suggestion is to lower the playable area to the level of the cave so if you go mining for some ores or looting, it will be without cost.
