Hi.
Very nice mod. I use it currently in Space Age.
But doesn't work with https://mods.factorio.com/mod/blueprint-sandboxes
When I switch into blueprint mode, your mod down with error.
Please, fix it if it's possible.

I'll need to see the error

Error while running event disposable-construction-robots::on_player_crafted_item (ID 13)
LuaItemStack API call when LuaItemStack was invalid for read.
stack traceback:
[C]: in function 'index'
__disposable-construction-robots/control.lua:15: in function <disposable-construction-robots/control.lua:14>

fixed

thanks a lot
