As per subject, the logistics system chose to deliver a damaged belt to my factory, but when it automatically attempts to insert the damaged belt that somehow confuses the factory or the inserter. The inserter cannot insert the damaged belt, as there is no room, but the factory cannot produce because the inserter has not yet inserted the *other* ingredients required to produce.

Here is a screenshot. Note the inserter that is stuck trying to insert a damaged belt into the assembling machine, just to the left of the open dialog, second assembler from the top.
Why is this a bug? A few reasons:
* There is no way for me to tell the logistics system to not bring damaged parts
* There is no way for me to tell the inserter to only insert non-damaged parts
* There is no way for me to get rid of the damaged part other than manually going there to pick it up
* The inserter is normally always intelligent enough to only insert ingredients when there is space for the item to be inserted..except for in this one special case.

Basically this causes a stealth-blockage in the entire factory line through a circumstance that I have very little influence or control over and cannot reasonably prevent, and there's absolutely no notification or indication that this is happening until I suddenly realize my red underground belts are no longer being produced 3 steps further down the supply chain.

Here's what I would except would happen, in this case:

a) The item should not be picked up, unless it can be inserted. Seems complicated to implement reliably if damaged belts are normally valid ingredients but cannot be mixed with non-damaged belts.

b) If an damaged item is stacked with non-damaged item under any circumstance where it cannot be reasonably avoided (such as here),the stacks should be merged and the damage normalized across the stacks, similar to how spoilage seems to be normalized across stacks. Seems simpler to implement and a minor compromise.
