Not sure what's happening but every time I play with this I get a CTD as soon as an item from a blueprint is laid out.

can confirm crash when the drones build something from a blueprint

Can you delete and reinstall?

I found a bug and quickly disabled the thing causing it, but some people had already downloaded the version

Construction_Drones_0.1.5

Getting the crash described above, here is the log.

I deleted and re-installed, but the crash still happens as soon as one of the drones attempts to build anything.

It seems to happen either at the object is placed, or the blue lightning bolt animates.

https://pastebin.com/qDMXVkV1 <<< Here's the paste of the log! Just deleted and reinstalled, same issue unfortunately.

I'm not seeing the bolt render, though I do hear the 'thud' sound of the entity being placed as the 'game as crashed' window pops up in the background. Perhaps the logic removing the item from the bot's inventory is related? I do find it odd that the anything within the lua engine is able to crash the whole game. Your mod is probably pointing out a memory protection failure in the game it self as well.

The bug is when the bot revives the entity, its been reported and should be fixed tomorrow.
The latest version, I uploaded twice, the first time had the command which caused the bug, the second did not. You should do a clean install of the mod and see if the problem keeps happening

I did delete and reinstall. Construction_Drones_0.1.5.zip is what the game downloaded which matches the latest version listed on the site and it does indeed still crash as soon as a drone picks up an item to build. Hopefully the update tomorrow will fix things. Thanks for staying on top of it.

i am also getting a crash as soon as the blue bolt is seen, i have uninstalled it via the mod menu, confirmed this in the mods folder and re-downlaoded it using the mod menu, and copied it to my server.
taking note of the MD5 checksum of both 0.1.5 versions before and after they were identical.
i will wait for an additional update to appear.

Installed it 20 mins ago without having it prior, still crashes.

I just installed 0.17.5 (mac osx steam client) and it works now. at least for me. So no more crashes. Thanks for this great mod !!
