Visual Bug

I was first alerted about an issue once i hovered over a Tin Cable (IC2 item) in the EMI ui, once the craft recipe guide gui opened up, it started absolutely spamming the following error: bug_error-stack.txt

This did not yet cause the game to crash, but instead it caused a visual glitch where the arms of my player in 1st person view disappeared along with any chests (and likely some other blocks, but i did not further investigate what else).
To fix this visual glitch, i needed to completely restart the game. I tried f3+T and /reload but neither fixed the glitch.

Crash

When i started to investigate more, i was viewing the Tin Cable recipe and once i hovered over any of the 3 buttons next to the result of the recipe, the game crashed and produced crash-2025-05-15_00.57.38-client.txt

Discoveries

• When i disabled the JEI mod, this bug and crash did not reproduce. But this does cause a lot of items not to point to recipe guides which is a requirement to include, so leaving JEI disabled is not an option.
• JEI does not reproduce any of these issues when disabling EMI.
• The visual bug only triggers when in anything that crafts, i think. at least not just in inventory
• the visual bug triggers on hover over the Craftables menu and when holding Shift in the Index

Note

I am aware that these items are from just one mod but i do not think its a problem of that mod as the error stack trace clearly points to EMI and the action that makes the game crash is not something that i would think IC2 usually would handle.

If i missed anything or if you like more information, feel free to ask here, ill lurk and will assist where needed to get rid of this, it is a game breaking bug that i would like to stop encountering for myself as well.
