The mod Companion Drones 2.0 (2.0.1) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event companion-drones::on_pre_build (ID 9)
Item is not blueprint.
stack traceback:
[C]: in function 'get_blueprint_entities'
companion-drones/script/companion.lua:1519: in function 'get_blueprint_area'
companion-drones/script/companion.lua:1557: in function 'handler'
core/lualib/event_handler.lua:47: in function <core/lualib/event_handler.lua:45>

Fixed in 2.0.2

Placing a blueprint directly works.
But I got this error when I tried to use a blueprint from a book:

Same thing, getting the error as well when placing from a book.

Yes I know about this, but looks like what worked in 1.1 is broken
I must find a workaround or better proper solution

Not son nice workaround found - fixed in 2.0.4
