I have searched to the point of being reasonably sure this has not been reported already:
on a 0.14.13 server that I have running from the command line, I noticed that under certain circumstances, I was getting more items from crafting than I expected. It seems that if, while I have the ingredients in my inventory, I (in groups of five) queue up 10 (or more, but for example sake let's say 10) inserters, and then queue up an equal number of fast inserters, followed by the same in filter inserters, my crafting queue sometimes (I've yet to figure out how to reproduce it consistently) ends up looking like this (a key element to this bug is that the perquisite items end up being queued up in higher quantities than expected):
15 inserters->15 fast inserters->10 filter inserters
if I then (again, in groups of five) remove the excess inserters & fast inserters, I often seem to end up with more products then I should for the ingredients I spent. Before I go any further with trying to reproduce this, does this sound like anything that's been reported? Might it be enough to pinpoint the bug in the code? Surely there's not that much code involved in manual crafting, is there?

Don't forget that some recipes produce more than 1 item and they aren't all needed to craft something. Like copper wire - if a recipe only needs 1 it will craft 1 set of copper wire and you end up with the extra in your inventory.

If you can show a really reproducible set of steps to clearly show the issue we can take a look,
A save game with the bare minimum of what is needed would be great, as it is the way you describe it, it is hard to deduce exactly where the problem lies

Thanks, but this is definitely a bug. If it's not producing free stuff then it's at least queuing more than I want.

Sure, I'll try to produce such a save tomorrow when I get home. Not sure when that will be, but we'll see...
as far as the steps, I think it was something along the lines of (working off the inserter example):
ensure you have plenty of gears, circuits, and iron plates (and note how many)
(while something else is crafting so you can queue everything at once) right click (assuming default keybinds) on the crafting recipe for normal inserters n-times (where n > 1), followed by fast inserters n-times, and then filter inserters n-times.
If I'm not missing anything (and I don't think I am, unless it's something that happened to the save and persists for an indefinite timeframe), your crafting queue should now display
inserter (n+1)*5x -> fast inserter (n+1)*5x -> filter inserter n*5x
and you will receive n*5 of each.
