The other day, before recommended build 1.1 was released, me and my friend made this big hole that lead to the void, and yesterday I downloaded the rb and tested it out on the server and when I warped to a certain area, that area always had a replica of the big hole we made, and the only way to get rid of it was to reconnect, so I covered up the real hole but did not fill it up, and tested the warp again. There it was. Anyway how to solve this from happening again?
