What did you do?
- Placed two inserters that insert onto a splitter from behind with an output priority set.
What happened?
- The output priority is ignored.
What did you expect to happen instead?
- The splitter should follow its normal output priority behavior.
Does it happen always, once, or sometimes?
- Always.

Re: [2.1.10] Output priority splitter not working when inserting directly
2.1.7 Changelog:
Observing this setup tick-by-tick with F4 option show-transport-lines, I cannot see anything wrong:
For comparison, the Inserter-to-Belt case takes 1 extra Tick to unload while it waits for the Transport Lines to advance, creating enough room for the 3rd/4th set of 4 Items to be dropped.
Good Luck!
- Inserters dropping items onto splitter always insert on the input lines.
