unfortunately I have no additional information. mythic metals is first listed in crash report, so I am hoping you can shed some light on this error.

I wanted to bump this since I'm also encountering this issue. Here is my log: https://aofpaste.com/fowicayijo.yaml

@KavisKryptic i just pushed a fix, which you can test by downloading the jar provided by GitHub Actions
Please let me know if any of you encounter this crash again

As of https://aofpaste.com/uyijojipeb.yaml we now know this issue is not caused directly by Mythic Metals.
There is something more to this tag checking that is failing, but we do not know what the true cause is, especially as re-producing it is really hard/random.

Yeah, I have tried attempting reproducing the issues multiple times. But it just decides to crash randomly when I'm testing my modpack.

I have noticed it happens when I have been using items from Mythic Metals (specifically armors & weapons, but that's probably just coincidence, not necessarily exclusive to those item types) or like putting them in my inventory. But I feel like that's obvious.

If there's anything I can do to help, let me know. Granted, I can't imagine there's much I can do to help.

Been issue hunting today. This is apparently not the newest issue around:
VazkiiMods/Botania#4027

New log. This one is interesting since in contrast to the other environments there way less mods loaded: https://pastebin.com/ANjq376s

I also have this error using 0.15.4
https://mclo.gs/40SS2pm
In Curseforge and Modrinth it is only possible to download version 0.15.5 by choosing manually, as apparently it is marked as only 1.19
Even at the moment I had the crash, the version already existed, I downloaded version 0.15.4 because filtering to only 1.19.2, version 0.15.5 does not appear

That is slightly unrelated, since 0.15.5 will not work on 1.19+, and hence is marked so.

Thanks for the log though

Unsure if you need any more crash reports for it to help narrow it down?

I am happy to announce this issue will be closed, as Fabric has merged a fix for it.
