So i tried to place an item into the hopper, but its falling straight into the chest :( Not sure why though?
copperhopper-0.0.3+1.18.1

latest.log

If you put 10 cobblestone in, 9 of them will fall through but the last one will 'stick' in the item filter hopper.

Is that not what you're seeing?

Oh. Actually, I think it's probably because you're using Lithium. Lithium completely changes the hopper code and Copper Hopper can't work with it.

(thanks for sending the log, makes things a lot easier)

I'll add the conflict with Lithium to the mod metadata.

...actually, someone on curseforge just noted that you can

Add "mixin.block.hopper=false" (without quotes) into the "lithium.properties" config file.
This disables the performance tweaks that Lithium applies to hoppers.

the new version will warn you in the log if you're also running Lithium. Best I can do, I'm afraid.

Nice! Did that, thank you 👯 Will try it out later :)
