[2.0.14] Inserter bug with recycler, not inserting into recycler that processed red chips

[MSgtGunny]

I created a small setup to delete items on Fulgora above a certain amount, but the logic when its recycling red chips breaks when given red circuits due to what looks like an inserter bug in relation to recyclers. The recycler has no items in its input, has red circuit ingredients in its output/result boxes, and a few items on a belt that lead to an inserter to put them back into the recycler. The initial input inserter that inserts the red chips is set to only insert if there are no items on the belt so that it doesn't get blocked.

It does not immediately lock up, but once the output belt is full and there are still items in the recycler result, the inserter gets locked and is preventd from putting an item into the recycler even when its input is empty. To quickly reproduce using my blueprint, turn the right inserter so it no longer is pointed to the recycler and temporarily disable the circuit On/Off condition on the left inserter, once the output belt is full and there are a few items in the recycler's result box, reset the inserters back to their original state.

Can you please post a save file that shows the issue you're describing? I'm having a hard time understanding how to reproduce what you're describing.

Sure thing, heres a slimmed down save with just the bugged setup on fulgora

[Rseding91]

Looking at the save it looks like two things interacting here to make it confusing:

1. The current recipe produces plastic when recycled but is not overloaded on the output (yet) and would accept more red circuits
2. The next item to insert is plastic but there *is* an overload of plastic so it won't insert it

With the two combined and because you've blocked loading more red circuits they both fail to insert. You need to wait for the recycler to have nothing in the output before blocking the red circuits from being inserted.
