Hey guys, my brother and I have been playing a LAN world (off his computer) for a couple months now, and I tried to join yesterday and it tells me "Internal server error". We are playing the old version of TBR, the one called "tbr-the-modpack" which has 137 mods, and is in 1.4.7. It's not on the platform website anymore.
Up until now he's been having crashes every time I try to join him if I haven't already attempted it, like this: We both load the game-> he gets into the world and opens it to LAN-> I attempt to join-> He crashes-> He get's back into the game, then from there everything works pretty much fine until one of us crashes while actually playing, after which we have to start the whole process again.
Also, this happens in other packs as well but we haven't tested vanilla. Funnily enough though, he can join world's that I host without any problems (not tbr though because that causes me to crash).
Any help with resolving this would be great:)
