inserters are stuck in "Waiting for source items" when circuit conditions change the inserter from "disabled" to "enabled" and belt items are stationary. moving the items "fixes the issue"
Possibly just being dumb, but my train in group "<sulfuric acid icon><number 4 icon>" interrupt named "load<sulfuric_acid" is not triggering unless I click on the automatic toggle twice to turn it off and on again.
Seems like a bug. I attached a save from right before the screenshots were taken ...
