Hi there!
I got the following crash after trying to update a blueprint (nothing interesting, it's just a 15/sec green chip stack). I placed the inserters wrong, so I changed their orientation. When I tried to update the blueprint, my game crashed with this crashlog. Thanks for your time! (the blueprint doesn't even have circuit logic or anything from this mod to begin with...).

The mod Button Combinator (vanilla style) (0.4.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event button-combinator::on_player_setup_blueprint (ID 85)
