Fish Traps - Not producing fish with traps.

How to replicate:

Place fish trap with a pipe connecting it to a storage chest. > Filter pipe to only allow fish through (yes you have to add every type of fish to the filter so pickles don't get parsed through)
Fill fish trap with pickles but leave 2 spaces clear.
Once durability reach's 0 on the fish trap it does not break, the durability goes back up to 100/100 but the trap does not produce fish anymore.

To see this in action, visit D22 on EU-Survival and see river. There are 5 fish traps with pipes connecting to storage chest.
