Cool idea. I hope this gets implemented in vanilla. But the bots just stay floating over the ghosts doing nothing for seconds and then plonk down the entities (concrete tiles in my test case though). I'm guessing CBCR is calculating how to group the entities to one or something. Probably not even your fault but a limitation to the mod API. As it is I can't use it though :/

Actually impressive that you got it to work though!

Nope, my mod only works when the robot build the entity, don't work before, maybe other mod?

When I disabled this mod (all other mods stayed the same) the bots behaved normally.

The game is freezing on this moment? Or only the bot?

Thanks for the feedback

Just the bots.
