Hello!

I was planning a modpack update ahead a little bit and noticed that Roughly Enough Items no longer functioned properly if any of the Malum updates from 1.4 is installed ( in Minecraft 1.18.2 ).

I'm not sure on the error itself, but I am inclined to think maybe the Water Necklace (Necklace of Tidal Affinity) is part of the issue.

When searching cobblestone in REI with Malum installed, nothing "moves":

When searching @malum in REI with Malum installed, it works:

When searching cobblestone again and Malum is not installed, it works:

Versions:
malum-1.18.2-1.4.3.1.jar
lodestone-1.18.2-1.2.jar
RoughlyEnoughItems-8.3.549.jar & Dependencies installed from the CurseForge App automatically
Forge 40.1.84

As mentioned earlier this might have to do with the new necklaces

The water necklace is this one (is this the intended texture also?):

I notice other necklaces share an "empty line" in REI (the description maybe?):

For instance this necklace does not have an empty line:

I believe this might also be an issue with REI, so I will report it to them and link the other issue here as well for convenience. Thanks for checking into it at some point!

I've spoken with the author of REI a bit the other day and they don't think it's caused by REI. They don't know why net.minecraft.world.entity.ai.attributes.AttributeModifier is missing, but they said maybe this is the wrong classloader:

I hope that helps

I've reported this to REI as well with as much info, please see linked issue and thank you ^

FYI, just used the combo today with both mods updated (as it's been a while), and the above was a non-issue

Alrighty, I'll take your word on it. I haven't been able to test this myself, but as you mentioned there's been quite a few updates since my report.
I'll close this then and assumed it was fixed, if I notice this again in the future I'll open a new issue.
Thanks gr8pefish for the comment 🙂
