That's how it always was, everyone was able to build a gold mine in temple holdings.

@Slayer Seemingly every damn place has a gold mine now. I'd recommend starting a game without the addon, then switching it on. Otherwise the NPC is going to have gold mines everywhere right off the bat.

Does this give EVERYONE with a chapel access to a potential goldmine, or just the player? Or just the players faction? I tried it out and it didn't give me the said "5 per month" it said it it would (maybe it takes time to build up to that?) and I'm pretty sure when I conquered another barony, it had a church with a gold mine already created.

A little more information about what it's actually doing and why would go a long way. I would prefer if I had the option to say "only for player/family/faction", or if that's asking too much, just a "player only" option.

I don't want my enemies to be wildly rich, just me.

is possible make in the castles ?
