Hi,

i just recently had this problem with deep resonance. @McJty luckily had this already fixed and a new version uploaded. This error happens when we now try to join from aroma mining world to the overworld (we have it running on a server). The server crashes then but the clients dont. Idk if this is because i just recently placed some universal cables in the overworld. Before that the error didnt occure.

Here an extract of the log:

This is a MCMultipart issue, the MultiPart container is not returning the ID properly.
