Issue with mods

Simply can't get any of the latest versions of the mods to work on my server - the crash log appear to refer to stonezone as the culprit, but I'm unable to determine the 'actual' cause. I haven't exhaustively tested mods as I need to keeps things running and am struggling for time. For now, I'm simply manually using older versions as per below.
I've attached the most recent crash log, maybe it can shed some light on the possible cause.

Apologies for the somewhat lackluster information.

In summary, these crashes my server:
stonezone-1.21-2.11.2-neoforge.jar
everycomp-1.21-2.11.3-neoforge.jar
moonlight-1.21-2.23.6-neoforge.jar
sawmill-1.21-1.6.1-neoforge.jar

These work fine:
stonezone-1.21-2.10.7-neoforge.jar
everycomp-1.21-2.10.14-neoforge.jar
moonlight-1.21-2.22.6-neoforge.jar
sawmill-1.21-1.5.25-neoforge.jar

I've looked into it and couldn't find out why. I believe SconceBlock is the problem. You should talk with DEV of Ars-Nouveau to see if there is anything that make sourcestone unique compared to other StoneTypes.

I'll blacklist that stonetype from ARS-NOUVEAU, so you can play without any problem with Additional Lights.

BLACKLISTED ars_nouveau:sourcestone in v2.11.3

Quick update; As a quick last resort, I ran the crash report through Gemini, who said this (among other things...):

• Stone Zone uses the Every Compat mod to create new block variants for compatibility with other mods.
• In this case, it is attempting to create variants for blocks from the Additional Lights mod.
• During this process, code from the Ars Nouveau mod interferes. A feature in Ars Nouveau attempts to apply a redstone "level" property to the new, unregistered block being created by Stone Zone.
• Since the block from Additional Lights does not have this "level" property, the game throws an error and crashes.

A quick rerun with the latest mods, but with additional lights removed - IT WORKS! However, I'm not sure if the actual error lies in Ars Nouveau, Additional lights, Stone Zone, or Every Compat? Happy to raise an issue where needed.

Thanks for the info. that's very helpful details.
