I tried to find a solution to refine further this feature, but determiners / algorithm responsible for how goes underground generation are not present in base game rpk files, but probably in .env files. The same goes for how you interract with province improvements on strategic map. Unfortunately env files are encypted in unknown by me software so i cannot read it in order to find anwser, tunnels wll stay that way unless game developers move more things to rpk files allowing for more versalite manipulations with.

Claimed tunnels block pathing for allies. No idea if that midpoint can be disabled or altered somehow, but would be nice.

Not sure if you're aware, but the Dungeoneering Conclave will change the tunnel provinces to dungeon, but it won't visually change the floor, roads, or walls. Not sure if this is fixable but it sure would look better.

Tx 4 the quick update!

翻译：这个模组让《AOW4》玩家能享受超大城市，提升了城市厅升级的吞并距离加成，并将最大人口提高到50，同时调整了食物供应阈值。现在，玩家还可以在地下隧道中吞并和建造省级改进设施，但需要新建游戏才能生效。模组有三种变体，区别在于人口上限（100、75、50）。此外，还有单独模组可单独启用地下隧道功能或移除吞并距离加成。

Amazing mod. Thank you so much!

I really appreciate your mods, thanks.

New variant is available, if someone doesnt like annex distance bonus, it can be removed now too.

Really not reason to refuse. I gonna upload additional variant of my mod tommorow, also mod allowing to revert bonus to annex distance from this mod if someone doesnt like it.

Hi SkyPheonixZ1. First off, good job and thank you for the great mod. Just wondering if you could make one with 75 max cap? Thank you!

No it doesnt

Hey, does the expansion part work for narrow surface ravines, too?

Oh thanks

if you want to set pop cap higher, you need also to provide values for the new labels in food supply thresholds, otherwise the game will crash as soon as you reach certain amount of population past mine pop limit.

Every my mod contains detailed txt file inside mod's folder as it describes the path to the certain .rpk file and its property you are looking for.

how do I change just the population cap? i don't want to change the food supply or annex range

Wohoo! Thank you so kindly!
