Do you know what effect that has on SMP? I will give it a try when I get everything updated. Dropbox was being a jerk today for me. I remember having a issue like this with another mod before but in SMP it really screwed up a lot you had to close the client for reconnects.
Also thanks so much and Merry Christmas!
The ID conflict thing? I don't know. In singleplayer I got a warning, asking me if I was sure I wanted to load the world cus there was an ID conflict.
First I thought I messed up the config or something so I pressed no and the client froze.
Then I realized it was the forge thing and I pressed yes and everything was the same as before.
I have no idea whether you'll be asked when starting a server. Shouldn't affect clients though. I think :S.
Merry Christmass to you too!
