Hello,
I know this should probably be in the Mods section, but...
I have been trying to start a server for a while (stupid port forwarding) and I am trying to load mods into my singleplayer world. However, when I try to load the mods, it fails, gives me an error message, and won't let me use the singleplayer world until I deselect the mod in the Configure menu. I am running 0.4.13(not dev) in Win 7 Pro x64.
Thank you
