Lines 659 to 677 are all errors. Can not copy and paste it due to horrible formatting on the page. My phone when highlighting it doesnt know what to do (next time please upload to a site that doesnt wrap text such as paste)
Also 1254-1297 are also errors. Both the errors are not sponge specific. The first looks like the developer didnt build the plugin correctly so MCP didnt apply.
Sponge is designed with the limits of MC in mind. So when a mod developer tries to do something that works but is unstable, sponge says “what’s going on here” and reports it to the console, normally in the form of a crash.
I can not seem to find anything like this here. Just a lot of messages stating that the server is behind ticks (normally implying that your trying to demand too much from what your running on). This could be to do with the error your having, or it could be that sponge is denying some unstable action from this mod.
Best bet is to get the errors fixed (maybe to do with them too), report it to the mod developers (and want on responses on this post … If there are any) and hope for the best
