Discord Moderator plowmanplow Posted December 29, 2014 Discord Moderator Share Posted December 29, 2014 TiCTooltips is a client only mod. Try removing that. The error here: Caused by: java.lang.NoClassDefFoundError: net/minecraft/world/World indicates that you have a client only mod in your server mods folder.

BossX Posted December 30, 2014 Author Share Posted December 30, 2014 That solved the issue! Along with using an earlier version of COFH Core, Thermal Expansion, Thermal Foundation, and Tinker's Construct. Link to comment Share on other sites More sharing options...
