We just loaded the new 1.5 and are unable to login, as soon as we connect, the game (client) crashed

The game crashed whilst ticking entity
Error: java.lang.NullPointerException: Registry Object not present: cataclysm:bloom_stone_pauldrons

crash-2023-09-21_11.34.27-client.txt

Fixed by reverting back to 1.3

This issue is still prevalent in patch 1.7 server as well

We had the same issue with 1.7.

Long story short, we copied the new files on top of the old files, so mods where loaded twice or bad/old versions first

L_Enders_Cataclysm-1.29-1.20.1.jar
L_Enders_Cataclysm-1.34 -1.20.1.jar

Both where loaded at startup.
Anyway we fixed by renaming the "mods" folder to "mods_old" and copied the new "mods" folder from 1.7 zip to the server, booted server, all fixed!

As far as i know, issue is fixed
