I changed version number in info.json to be able to play with the mod.

Setting blueprint-book to -2 crashed the mod. Trying to figure out how to use the mod properly but the documentation has a lot of gaps. There's no inventory slot for a blueprint book so I'm unsure how to use those, though I believe I might have used conman for this before. Or maybe it was Recursive Blueprints?
The documentation doesn't say that you supply the entity as a signal = 1 to build it (without blueprints).

(Another bug: Also the entity build order places ghost even if there's a collision. So you can have 400 ghosts of assembler + 1 assembler on top of eachother...)

The mod ConMan Construction Manager (0.18.4) caused a non-recoverable error.
Please report this error to the mod author.
