There's a hole as soon as you warp to mine I and i fell though it ;-;. I didn't know where to post this I'm posting it here because it will get the most attention but this might want to get looked at. http://imgur.com/a/Uc8uT
I sent Cyp a message about the hole at /warp E (and I before it was fixed). The holes apparently keep showing up, and we don't know why. If anyone has any insight on what's causing the holes, it'd be a big help.
I have no idea what's causing them, but there's now a hole at /warp M and /warp N and still at /warp E.
