Hello,
thanks for the nice mod. Unfortunatly it has an incompatability with orbital ion cannon that crashes the game.
when firing an orbital ion cannon the game crashes with below mentioned messages. Ion cannons work somehow like an artillery, hence the event call, but are launched into space and do not exists as object/buildings after launch. My guess is that you have to wrap a event.source ~= nil around your logic in the replace_biters_from_artillery_with_quality function.
The mod Ancient Knowledge (0.1.2) caused a non-recoverable error.
Please report this error to the mod author.
