So In a modded SMP server I play on, I'm getting ready to massively overhaul my AE system, add more storage and more slots for machines, part of that was automating processers and crystals so I set up sub networks to do those two things
I used this set up for the processers: https://www.youtube.com/watch?v=e_isR_UfnDE&t

And this set up for the crystals:

My main system is two drives with 15 64k drives, a controller with the three interfaces for crafting making patterns and putting the patterns in the system. I have a single CPU still, was making more when this happened, I looked around and saw that Redstone being duped was a problem with the formation plate, took that out replaced it with a storage bus and a precision dropper in the hopes that that would fix it but it didn't, When I go to craft the pure crystals it doesn't show what is needed for the crafting just the finished product, with no way to get to it. I tried to make the 33 controllers I needed in order to make my new system and this happened so If anyone can shine a light on what I can do

Additional context

This is the Pictures of how after I take out the patterns and completely destroy the interface that holds them in the system before putting a brand new interface in the same spot and getting those two patterns in my system that do nothing.

I am playing FTB revelations version 2.5.0

everything is set up correct, there's nothing missing and yet the crystals aren't crafting, I can craft the fluix crystals, but not the pure variants

Environment
This has happened in both the overworld and the storage cell I'm going to be storing my AE system in.

• Minecraft Version: 1.12.2
• AE2 Version: appliedenergistics2-rv5-stable-11
• Forge Version: Forge-14.23.4.2759

Rv 6 is the latest stable, try it out please

And a full modlist next time please :)

Don't know exactly but make sure to update ae2 reated mods too if present

Make always sure to have enough energy cells (the ae2 ones) installed because input is limited by System energy cpacity

the problem is you describe an issue that may have already been dealt with, so updating would be the oinly step to verify this being an still persistent issue ... nothing we can do for you unfortunately except recommending to

do a copy of the world and modpack
enter the modpack profile settings, disable the lock button
view the modlist and update all mods related to AE2 to the latest version

and check if the issue is gone (but maybe due to changes in how things work others may break)

Its part of a mod pack so I cant try out the latest stable build. the full mod list is in the 200's so I didn't want to waste my time and yours listing them all out

==============================================
I cant do anything, updating wise. I reported the issue here because I thought that maybe someone would have an answer for what was going wrong, I would still like an answer bc I will continue to use the same version of the mod until the modpack that I am using updates to rv6. and updates all related mods as well. I have energy cells hooked up to it if you took a look at the images you would have seen that. I apologize for sounding hostile I was just expecting more than 4 lines of text that don't help at all. I would really love to see what the mod developers make of this problem. if they would download the mod to see the bug themselves I can get them whitelisted on the server that I'm playing on. Or if you want me two I will run through the whole process of making my set up in creative and record the process and when the bug happens.

I did what you recommended and I can verify that it is a persistent issue, updating the mod to the current build does nothing.

This is pretty much a user error like using the wrong pattern type, not returning the result or similar.

@ToxicSnow, do you use level emitter within your configuration for controlling growth accelerators? It seems, that level emitter with inserted crafting upgrade and mode set to "Emit redstone to craft item" lead to the problem you described. Switching mode to "Emit redstone while item is crafting" solved the problem in my case.
