I have come accross a strange issue with autocrafting certain Items that include buckets in the recipe. I am aware that this may be an insulated issue with a specific mod - Thermal Foundation - however, right now, I think it's a Refined Storage issue.

When I try to auto-craft the special TF blends (Signalum, Lumium, Enderium), the process gets stuck on the crafting part with the message "No Machine Found" in the Crafting Monitor. Then, after I remove the pattern from the crafter for a short moment, the crafting instantly finishes and the output can be found in the system.

• Minecraft: 1.12.2
• Forge: 14.23.0.2512
• Refined Storage: 1.5.20

Issue occurs on a server.

I had the same issue, but when I disable oredictionary mark in pattern grid, it repairs!

Is the pattern a processing pattern or a regular pattern?

I have tried with both variants, and got the same result.

Are you having a duplicate pattern in one of your crafters?

Just thoroughly checked through the whole system, and haven't found any duplicates

I'm not sure if you worked with structures before, but here is a structure file with all the parts needed. Should work with just Refined Stroage and Thermal Foundation installed, however, I don't know how well structures work with mods.
refinedstorage.zip

Refined Storage doesn't support exporting to structure files.

Ah, I wasn't aware of that. In any case, I reproduced it in a creative world on an insulated system.

Making new report with detailed issue description - it's a critical issue.
