[Bug] Combiner Stuck when Interface is Not Open

[bcrotty]

I'm playing ATM8 (1.0.18) with Alchemistry-1.19.2-2.3.0. I'm trying to make Reactor Glass, and I have a Combiner that's alternately getting fed SiO2 + PbO or Pb + O using an AE2 pattern provider that doesn't put new ingredients in until the Combiner input is empty.

When I have the Combiner interface open, everything happens as it should, and the Combiner recipe switches back and forth between the Reactor Glass output and the PbO output. When I close the Combiner interface, I think the Combiner is unable to switch recipes, so the current recipe will finish, but then nothing happens. The FE does keep getting used up, but nothing gets output. When I open the interface again it starts the other recipe that I didn't see the previous time.

I had a similar issue when I tested it with AE2 (same pack with minor modifications, same Alchemistry version), just with the fusion reactor instead. I switched over to using Refined Storage (for lag-related reasons, mainly), and it's working perfectly fine with that, so I'm suspecting it's something to do with the way that the pattern providers insert into the Alchemistry devices, whether that being inserting too fast or whatever it may be.

Curiously, when I was using AE2 to do things, I actually had a similar, but slightly different problem, where occasionally the items would be in the reactor, but even viewing it's interface would not cause it to process - so my guess is it's something regarding how Alchemistry sets the recipe for the devices, and AE2's speed may cause a bit of a problem with that. That's only my assumption though, so definitely could be something else even more technical or something, but just adding in that I've experienced it too, with other devices, and it seems to be something between AE2 and Alchemistry.

@Timbroglio can you attempt to replicate this and gather info? I'm not convinced that it's an issue with Alchemistry. But if it is, I can look into a bug fix.

I got a Similar Issue on the [1.20.1-2.3.0] Version when using Pipez 1.20.1-1.1.3 - when the Pipe inserts the items into the Input if the Combiner - it consumes Energy as it would work, but the progress bar just starts after you opened the GUI, which in combination with #316 crashes the game - After relogin(Server) the full Amount of Input Materials have been sucessfully proceeded and pulled out.

I am unable to replicate this issue. Here is the test I conducted:

• Setup a combiner with pipez inputting one side and outputting another side. Another pipe for power.
• Set the recipe to Acetic Acid.
• Put 64x2 oxygen, 64x2 carbon, and 64x4 hydrogen into a chest connected to the input of the combiner.
• Don't open the combiner at any point (after setting the recipe).
• Open the output chest connected to the output pipe. I saw 64 acetic acid when it was done processing.

The combiner does not require having the gui open for it to process.

It's possible that there is some issue with AE2. Alchemistry however is using the standard forge item handler and casting the item handler when the capability is requested. It's really the only way to do it. It's possible that AE2 is doing something unorthodox or has some buggy interaction, or that there might be some issue with pipez or anything else. But the issue does not appear to be with Alchemistry.

If anyone can provide more information, a stack trace, or a way to properly replicate this issue that does not require a modpack, that would be great. Keep in mind that I cannot load a whole modpack in development mode. I can load a mod or two to test for compatibility. So if you can narrow your issue down to as few mods as possible and write a step by step way to replicate the issue, I might be able to determine if there is an issue with Alchemistry or some other mod. But it's unlikely that this is something I can fix (especially without more information) because it already works correctly.

I have retried this today - the actual problem is switching unlocked recipies without opening the GUI. / having the recepie automatically set by the items that have been put to it's input slots. if you set the recipie before, it runs fine for that one recipie.

Steps to reproduce:

• Setup the Combiner as u did
• Set the Recipie to "minecraft:apple" , insert the 64x Sucrose + cellulose into the input chest
• All Apples will be successfully produced and get filled into the Output chest.
• After that finished - We put 64x Cellulose and 32x Oxygen into the input Chest -> Output Chest remains empty until GUI gets opened manually and the Recipie switches and the process begins.

Even if the Combiner has no recipie set when it is freshly placed, it will not automatically start with the corresponding recipies. Setting one fix Recipie for one Machine would make automatisation much more complex.

Thanks for the info. I will need to attempt to replicate it now with your instructions.

@Dark-Arcana do you know if there is an update on this bug? it is very frustrating to do multiple recipes on a common set of combiners even if i have the correct ingredients in the combiner, it won't start until i open the interface. this makes autocrafting impossible. Please and thank you!
