Hello, I've recently received a new MacBook Air, with OS X Yosemite. The other day I downloaded block land and everything ran fine. I played on servers and more importantly MADE servers. Today I tried to make a server, but no one joined. I asked my friend, and went to see the problem on my other computer, to see what the problem was. We both found out theres no IP. What is this madness? I thought the update didn't require of port forwarding and it was working perfectly. Was it because I got a few add ons? if this is the problem I could post the list of what I recently downloaded. Anyways, a big helping hand would be appreciated. Thank you!
