Hello, I've recently upgraded my storage system to App. Eng. and I'm having a slight issue, i have 4 chests on 1 side (2 64k drives and 2 16k drives) and the other side of the room has 4 chests, only 2 have drives (16k). all 5 locations work with my enderchest + filter design, except my blocks chest (16k), the filter is in a permanent redstone on state, even though i have a timer pulsing every second, the drive isnt full and the pneumatic tube isnt broken in any way, but when the tube is broken, the filter shoots out items just fine, any ideas on what the issue is?
