This is in version 1.1.80 (build 60618, win64). I'm on the final tutorial and didn't notice this issue in previous tutorials, so I don't know if it's tied to this specific level somehow.
Basically, when a belt I'm using to transport materials to put into an assembler or furnace gets completely backed up with that material, inserters will sometimes stop taking them. All the other materials/fuel/power the building needs are available. Also, I'm outputting the product to leave room for more, so it's not that. The inserters just stop working for no reason I can tell. If I use the "F" key to pick up some of the input materials and get the rest moving the inserters will immediately resume grabbing (at least until the belt is full again).
This is causing serious problems, as it means my production keeps grinding to a halt unless I stick around and babysit.
