I'm experiencing a bug with underground belts, wherein the belt will 'swallow' an item until another item is ready to exit the underground belt. I've included a link to a .gifv to explain what I'm seeing:

I hope this helps. If more information is needed please let me know and I'll help as much as I can.

Noticed this as well, except with piercing round magazines, first thought the inserter was somehow multiplying them but noticed they got delayed in the underground belt.

I noticed it when I saw the two red science packs bunched up together, and was like "wait, that's not possible..."

Thank you for the report, this is now fixed for the 0.11.2 release.
