Hi there. First of, I found this mod after you made compatibility for my planet and that you for that. it is so usefull that after a while I made it require dependency so if you had spike of new users a while ago, that could be caused by that.

Someone recently found out that combination of mods K2SO + Pelagos causes issues with recycling recipes (Empty barrel recycle into filled one)
I was unable to fix it on my side.
Today I got raport that this might be caused by barreling group so here I am

I don't know how to fix it but If I can help somehow let me know
