We've just release a moderate sized update so I expect some bugs to pop up. Please be detailed and give the exact error if possible.

If you're reporting a bug that you've already brought up once in the other thread, please explain it in full again so I can keep track more easily.

Since updating and going back to my previously established save file, my Companion Drone (singular, as I am in Challenge Mode) has seemingly become inept. It'll do the occasional deconstruct I queue for it, but otherwise it just.. doesn't. Do anything. Sometimes I need to put the stuff in it's inventory itself, sometimes I put the stuff in and it just refuses to build either way.

Reset-Companions only works to make the drone deconstruct like regular again. However, it no longer likes to pull anything from my inventory anymore, nor place things.. or repair things. It might be worth noting that I currently have a mod on that is increasing my inventory slots WAY over the regular.

Very strange. I'll take a look see what I can figure out but I'm not sure what I can do since my companion is behaving normally. Can you upload a copy of your save somewhere and give me a link? That will help me diagnose.

Okay so on my machine, the drone deconstructs just fine all the time, but when personal roboport is disabled, it does not construct (I never noticed because my personal roboport is always on). Does that line up with your observations?

I've just released an update that fixes this problem, let me know if it fixed yours too.

After installing an update on my already ongoing save, every time im trying to place a new drone I get a crash with this text:

The mod Companion Drones 2.0 (3.1.1) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event companion-drones-mjlfix::on_built_entity (ID 6)

Okay, I am out of town but I'll take a look at it as soon as I get back, probably Wednesday evening.

Also them seem super cracked after the update, they are working much faster than usual, it's fine on singleplayer but on multiplayer my friend is lagging hard when he or myself let drones build/dismantle a lot of stuff at once, at the moment we have 2 drones each(4 total) with 10 ticks interval, but I don't think it matters in this situation.

Multiplayer is not safe, as it says in the description. There are too many global variables from the original mod author that need to be refactored into player specific tables, it will require a major refactor to make it multiplayer compatible.

I'm having the same issue as Shadovek with the crash, will look to downgrade for now

Did you do anything with how their lasers work now? Before 3.0 they were pretty conservative with it's usage and only used them on specific items that were to be dismantled, right now I've noticed they are using shit ton of them even if there is less than 100 items to be dismantled, it looks like a spider that crawls towards their target (however dumb that sounds), I think that's the reason why them seem much more powerful but laggy in the current version

Something weird (and fun) happens when I craft a second companion. It acts like a god companion that has infinite reach and infinite laser hands and start working on everything that is pending at once. It would be cool if it wasn't for my potato laptop that cannot handle this greatness

...That's... weird? I have no clue how that could happen lol. What mode are you in, in the settings?

hahah is super weird.
I tried all modes, from 0 to 3. Probably is related to my other mods (have a lot in this save). But my only suspicious is with Bodyguard Companion Drones. Will do a test without that mod.
