I found some weird behavior with Actually Addition's coffee.

Using modpack Modern Skyblock 3, version 3.3.1.4 (which uses SOL:carrot 1.12.1-1.3)
I drank a coffee with no modifiers, and it was marked "eaten".

Then I brewed myself a speed + fire resistance coffee:

• it was "not yet eaten". (so far, so good)
• it stayed "not yet eaten" even after I drank it ... multiple times.
• the /sizefoodlist was incremented multiple times.

I did not push the tests too much, because it is my main game (and it is 1 am). I may do some more tests tomorrow.

This is interesting, will have to investigate

The new update just got approved on CurseForge!

Feel free to reopen this issue if you feel it's not yet adequately resolved :)
