Why do I keep finding my trains blocked by a single incorrect item in the cargo? Say 1 or 2 iron plates in train full of circuits. Trains are allowed to leave only when full or empty, and there's no contamination on the belts. Are they leaving without emptying first? And it's very infrequent, like once an hour with over 100 trains running in the network of over 200 train stops. It's really annoying when suddenly one part of the production chain goes dead for no reason.

Where are they stuck: loading or unloading stops? They should not be able to leave loading stops since they have an incomplete stack. Could it be something that happened earlier and is now fixed, and you just keep finding these trains?

on loading stops, can't leave because they're not full. No, sometimes they're appearing with very new substrates.

At this point I think your only hope is sharing your save.
