[Bug] OptimizedInventories true, hoppers cannot push item into dropper

[aria1th]

hopper is directly facing into dropper but it does not pushes item into it. Hopper is not powered by anything.

Which version are you using? If you are not using the latest version, please update to the latest release https://github.com/2No2Name/hopperOptimizations/releases.

[aria1th]

I'm using the latest version. I found all options are true, not only optimizedinventories. It happens when hopper have consistent flow of in & out, when it tries to push item into dropper.

I cannot reproduce this by trying around. Can you provide a world download, schematic or structure block file, so I can debug using the setup you have?

It's ilmango's fast acacia farm-based, with shulker loader. I placed spruce tree by 36tick interval, and afked for 4 hours, and by some point hopper failed to push items into dropper. I don't know it is the cause of the server crash, but server crashed due to [23:05:13] [Server Watchdog/FATAL]: A single server tick took 60.00 seconds (should be max 0.05), After the crash, server admin has disabled the mod, and hopper worked as it should be.

I actually found that not only the tree farm, but also some kind of droppers repeatedly getting triggered and getting flows horizontally from dropper would make problem. All dropper/hopper did not had chunk border problem, and it's built on spawn chunk, always loaded by carpet fake player.

Mods used : fabric -Carpet 1.3.23, Carpet extra 1.3.18, Lithium, Phosphorus, Servux, hopperOptimizations ; MC java version 1.15.2

I've successed reproducing this bug, with OptimizedEntityHopperInteraction true + OptimizedInventories true + OptimizedItemStackEmptyCheck true. It is world file.

Middle hopper-dropper line is bugged, hopper is full of bonemeal but does not send any of it to dropper.

I still can't reproduce it, ran the farm for half an hour, and did not see any problems besides the shulker box unloader being too slow for the farm

[aria1th]

I thought that dropper was 'stable' blocked... maybe using tick warp command, I reproduced it with tick rate 300

Reloading the map/server actually solves the problem, but it still occurs. Actually shulker unloader is intended to be slow, farm runs less than 1/3 speed (36tick). I refilled bonemeal and summoned fake player, and set rate 300 and it occured again

[aria1th]

Reloading world / restarting server solves the problem, but I don't know what's happening.

[aria1th]

Found that just having chest-hopper-dropper/dispenser with constant flow can jump into problem randomly, with very long period of time... I guess it's cache related problem. Not only in my computer, public server(fabric +carpet mod) had the problem. It is solved when server restarts, which means it do not save blocked state.

I made this contraption with an upwards facing dropper and the observer clock. I am tickwarping it and I am not encountering the problem. Do you have a minimal setup that reliably gets into the broken state after some time?

[aria1th]

general_craft.zip I added tons of hoppers connected and used autocrafting module, and tick warped for a long time. I'd add schematic soon. I don't think it is reliable but seems like time does matters

[2No2Name]

There were many changes in the latest version, I believe this should be fixed now. Can you test it again, please?

[aria1th]

seems okay, Not found any stopped hopper

Thank you. If it occurs again, just create a new issue
