Both copy/paste and any blueprints from books (or just saved as normal ones) now crash with this:
The mod Companion Drones 2.0 (2.0.4) caused a non-recoverable error.
Please report this error to the mod author.
Error while running event companion-drones::on_pre_build (ID 9)
companion-drones/script/companion.lua:1522: attempt to index field 'cursor_record' (a nil value)
stack traceback:
companion-drones/script/companion.lua:1522: in function 'get_blueprint_area'
companion-drones/script/companion.lua:1573: in function 'handler'
core/lualib/event_handler.lua:47: in function <core/lualib/event_handler.lua:45>
Ghosts (and copies of ghosts) both work fine, though.
EDIT: Turning off the bot construction and putting down the blueprints/pastes before turning it back on is a workaround.
