Describe the bug
There is a repeating error message in my code which leads me to believe it will cause lag for us.

To Reproduce
Steps to reproduce the behavior:

1. I launch twitch App
2. Select my modpack (TLOSFReduxExtraBeef_1.0.8)
3. Select play (purple gui button)
4. the minecraft launcher window appears
5. I select the correct version to launch
6. I launch Minecraft
7. loading of mods takes several minutes
8. I eventually crash (because of an unrelated issue with the mod: Embers Construct (that issue is resolved)

Expected behavior
I expect there to be no errors, and to not consistently and repeatedly give errors related to loottables.
