Situation:

• You have a factory producing some item which needs more than half the stack size of an item for the recipe
• You fill the factory via a chest which has 3 stacks of the needed item
• The item is not the last one in the recipe
• Your the needed amount of items to fill the factory after producing an item is not a multiple of your inserter stack size bonus

Result: The inserter will remain with at least 1 of the items in hand and will not fill up the factory resulting in getting stuck

Solution: The inserter should not try to insert more than 1 stack of any item into a factory

Yeah, it is a known issue that any item that requires more than half a stack size to be built causes issues.

Another one is if the stack size is less than 10, EG 5, you get the same issue, since with maximum inserter capacity research, it will pick up 5 at a time, and try to place all 5 in the machine, if the machine already has at least 1 in there, you get the same bug.

For this reason a lot of items that had a stack size less than 10 were increased to 10.

And still needs fixing.

kovarex said it'd be fixed, just not in the 0.11 build.
