Hello all,
I've got the exact same problem only for attack of the b-team. I start a Lan world to play with my room mate and he can't see it. If he starts a Lan world i can't see it. We tried direct connect with the IP but it doesn't work neither.
Lan world is working for a regular minecraft game and for the mod Hexxit.
If you had the same problem and know how to resolve it, please share
Thank you!
