The mod Colony Builder (0.2.4) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event ColonyBuilder::on_init()
core/lualib/production-score.lua:50: table index is nil

This is a crash caused by a vanilla Factorio script. My mod only uses it to calculate prices for the trading system.
