When I play on my PC Laptop or desktop it downloads multiple DLC of the same kind then it makes it so friends can't join the realm because of reasons unknown. id really appreciate any help because as of right now 4 months of work on this server is going down the damn drain and I'm kinda pissed not going to beat around the bush. I absolutely need an answer or a fix. I've spent too much time and money on this game just to let it go. plus it is almost worth the frustration of starting over.

PLEASE HELP D,: 

Also, with or without add-ons when jumping up in a 1x1 square I frequently find myself being booted off the tower I'm actively making. I see it ALL over the internet and WE know its only bugrock as the youngins call it
