[14.20] Assembler refusing insert onto size 1 stack

[clusterfack]

Summary Picture


General Description
As you can see in the image above, the inserter is trying to insert a stack of conveyor belts into the assembler. However it will permanently hold the conveyor belts over the assembler without inserting them.

When it happens
- It only occurs when the stack size in the assembler is 1 for some reason
- I have only seen it happen with this particular product in my factory I have no idea whether this is exceedingly hard to trigger or if it has something particular to do with this recipe

First noticed this in 14.18 and it continues in 14.20, I have never checked this on earlier revisions.

The belt in your assembler is damaged, therefore it does not stack with the belt of the inserter.

No the belts are being supplied from a requester chest directly from the newly assembled belts. Oh you mean the belt that is already in there, that's interesting. I'll have to check.

Ha! I think that was the problem, the health bar is almost invisible at my screen resolution so I didn't notice it at all. A partially damaged one must have come from my logistics network when I was deconstructing portions of my factory and then screwed up the production line. Spooky.
