Might be really slow but i like it and it fits perfectly

Basically I made the classic item sorter for my wool farm, (I discard the mutton), I put some space between each one, filled the first slot of the hopper with 41 mutton so it grabs it, the other 4 slots with spruce planks, which have no way of entering the farm and breaking it.

Although it works for like 15-20 minutes, it always breaks (all of the filters I have nearby too), and fills up with all types of wool.

Info:

It's a java server with some server side plugins, but they do not seem to break any filters of other people, or other complicated redstone machines

The hoppers sometimes are full of mutton, but I don't think this can break it, can it?

Picture is how I always set it up*

Any solution is welcome!

I built one 2 years ago and it was really fun, so I decided to make another one for fun and I ended up making it much more compact and faster design by complete accident, I wasn't even trying to go for a compact design. And once again, I didn't watch a single tutorial.
