Playing with friend yesterday, we noticed that bots behaves like crazy - swirling back-to-back, not placing items, waiting too long to place item from hand, sitting in inventory while there are tons of work around. And this happens exactly in multiplayer sessions with another players.
I just check this being single in multiplayer mode or in single mode - everything works like a charm..

If you need someone to test this - just say. I'm ready to help.

Which version are you using?

mod 0.1.13, game 2.0.73

Also, are the ghosts you're wanting built placed by other players?
There is a setting in the per player options to turn off doing other players jobs

No matter is there ghost or just deconstruct tasks. The settings set up to disable doing task from other players. I know about it, yes. But there was mine task and we were on very long distance with other player, so bots can't be affected by them.

pathfinding was updated in 0.1.11. Do you know is this was happening before then?

i'm not sure was i played in that time. especially with someone...
but i can test it on previous 0.1.10 in multiplayer with my friend and let you know the results.

If you can, please test this version and let me know if you see any issues.

If you can, download the https://mods.factorio.com/mod/some-luaconsole mod.
And run these commands in that console: (CTRL + ] keybind)

remote.call("construction_drone", "debug", true)
remote.call("construction_drone", "trace", true)

And if you see any issues, send me the log file.

You can contact me on discord if want, same username as here

hoho, now they operate almost worse then it was on our multiplayer session))
here is the log https://limewire.com/d/scPQH#hD54v37qEE

same actions done

I'll have to look into this. I'm by no means an excellent Factorio modder.
I only took this on because the older version didn't support quality items or some basic QOL features.

Some of these more advanced issues are a bit more complicated for me to test reliably and predictably.
If this persists, I'll probably revert some of the recent changes and just focus on bug fixes if there are any.

hmmm, is there any reason to add quality? i think they pretty good as is. just only if someone will request this support

There was a bug that non quality items would be placed on quality ghosts

And non quality items would be returned for quality deconstruction

And quality drones in inventory would not get dispatched

here the last 10min of gameplay when they start to stuttering... they can't build, can't deconstruct, moves around back and forth...
