There seems to be a bug where bots sometimes skip or repeat items in their to-do-lists and then get stuck when they can't complete the next ones.

This is most notable for me with a bot that I have set to make metal:
repeat:
    go to ore storage
    take ore
    go to furnace
    place item
    go to charcoal storage
    take charcoal
    go to furnace
    place item
end repeat
I often come by and he sits there, trying to put another ore into the furnace when in fact it would require only charcoal.This bot is the only one who accesses the furnace (no other bot and I don't use it manually).

The same thing happened when I tried to have bots first produce, then store wares (bring two logs to a furnace, then bring the charcoal to storage/ cut up a log and bring the planks to storage/ ...) - they just seem to jump around in their instructions sometimes. These ones I managed to fix by strictly restricting bots to one task (one bot puts logs into the furnace, the other takes the charcoal away), but that seems uneconomic and doesn't work well for smelting metal as the two bots who want to put in coal and ore often block each other.

So far I have not been able to observe this happening on-screen, so I can't pinpoint any possible reasons (i.e. running out of juice mid-action or being blocked by another bot traversing their target or something), but I'll keep an eye out.
