Seems this is hardcoded too, GRR, or in some obscure xml location.
@Devs - Either remove this or give us the optin to edit it out ffs. Built in cheats do not go in your favour, and yes it a cheat, its free with no reason given (Not linked to Ability, Trait, Event, Improvement or Ideology), just appears out of thin air. #extremelyanoyed
This now also raises the question if one thing can just appear out of nowhere, how many other's are there that the player does not see? So many reports of AI got this or AI got that, AI magicaly gain x. And you wonder why people slate the game for cheating?
^^ This is why its a bad idea just to give stuff for no reason. Now we know it happens, not good man, not good at all.
