Just an FYI, playing Krastorio 2 and upgrade to the latest 0.5 caused drones to stop working, no activity.
Roll back to 0.4.11 fixed it.

There was a button added to toggle them on and off. Mine was set to off by default. turned them on and they work fine now

Oh, really ? where's the button ?

In the menu on the upper right of the toolbar. Click the 3 little vertical dots.

Yep, thanks, that was it, hidden behind a bunch of toggles I dont use/need

You know what it still seems bugged. The drones are working but not actually building everything. They seem to stop halfway through.

I added the button to my toolbar to toggle construction drones. If you toggle them off and on they will make another round. Seem that they don't redeploy and finish. They go out and come back and then stop.

If there are a lot of other jobs (ie, lots of other ghost entities) then it will have to loop through all of them for the 2nd wave

What I am wondering about is how reach affects this? For example with Krastorio I am using the "far reach" option and there are similar mods for this. I guess with a longer reach more ghosts have to be looped through? This might affect performance for some people.

Player reach has no effect

Before the latest patch the drones were working really nicely for me. Never got stuck. Now I have to toggle the button off and on constantly . When I run out of an item, go get the item, and return, they don't deploy everything. I toggle and they finish.

Same redeployment issue. Whenever i need to build something, drones only deploy once blueprint is placed, they DO NOT go for the second cycle. This becomes obvious when placing multiple small blueprints — bots finish them halfway through. This does not happen with deconstruction.
I'm also using Krastorio 2.

when they deconstruct sometimes they get stuck on loaders like they are marked and the red beam is displayed but the entitiy isnt deconstructed

If you can provide your save games I can look into the issues.

Thanks!

With the 5.0 installed i noticed that the drones stopped repairing stuff, which was working properly before. Someone noticed the same?

I found an issue in the saves related to the check functions getting stuck on a bad index. They should work better now

btw, thanks for the Pause functionality !

Seems to work fine now. Thank you!

Working perfect again! Thank you so much for such a quick response, @Klonan!

thanks for any and all fixes you do, and even more so when you do them so quickly.

but does this fix refer to the original problem of this thread and/or also to what smeagol001 wrote (drones getting in a loop with the red beam flashing when trying to deconstruct something over and over again). i had the same problem (although not on loaders, but on pretty normal assembler2) already many versions ago, then not hit the problem for many weeks, and just today i once had the problem again (before updating to the newest version from today) ...
