My friends and I made a kitchen sink modpack and added universal tweaks to it.
Our consoles keep getting spammed with this error.

If anything else is required to submit the report let me know

Is it really caused by Universal Tweaks?

From the log, it's Had Enough Items complaining about Minecraft Transport Simulator's JEI interface.

I am actually not too sure, it mentioned Universal Tweaks to I figured I would post here... Either way I have to relay this to MTS devs, see what they can find and I'll report back

I mentioned this issue to MTS dev, hasn't answered at the time of writting this message, but when I was checking my latest.log to see if I got any other error I found this

Mixin apply for mod universaltweaks failed mixins.tweaks.misc.buttons.anaglyph.json:UT3DAnaglyphMixin from owner universaltweaks -> net.minecraft.client.gui.GuiVideoSettings

Here's the full log

That's just the 3D Anaglyph button tweak failing silently because OptiFine is installed, nothing to worry about.

This is indeed a bug with MTS. Y'all can close it out and I'll handle it on my end..
