if you have 2 nozzles same, then quite often the feeding is incorrect.
Most often it doesn't simply feed, and then you get into a loop where you press cancel to retry, it tries but doesn't feed before it tries to pick up the part.
I also noticed that when I upgraded the upgrade (?) caused the feeder to get 0 in feed time (on almost all my west feeders and some East feeders).
I have also noticed (and filmed, see my films linked below) that it feeds every time sometimes on an 0402 feeder where it should only feed every other time, it happens only sometimes, and if it happens, a reboot will fix it...
it seems to be related to the strategy pane, since if I change the order, feeding will be screwed up. (like go from 1 head to 2 heads, then in the list sort on nozzle size.
