Tested with build https://github.com/CaffeineMC/lithium-fabric/actions/runs/3038168288

Issue occurred when using Set Based Unloader Array. At the input handler shulker box arrives too late for recombining and drains a filter item.

How to reproduce:

• Download any version of the set based unloader
• Input shulker box with any stackable items
• Box is spit out to the side instead of being processed further
• Do the same steps without the mod to observe correct behaviour

Thank you for reporting this. I think this should be fixed in the latest commit which I just pushed.

That issue is still not fixed.

Thanks for testing again, fixed it now and also tested the setup. Issue was that powered hoppers started to sleep and then while sleeping started to sleep again, which made them not wake up properly anymore
