Terraformer

Yeah, tunnel tiles are pretty much a game-breaker for subterranean cities.These tiles cannot be altered by any terraform spell including "Dirt Cavern Walls". Also the tunnels tiles have a higher movement cost than the dirt cavern walls they were created from.

I was trying to find what was making tunnel tiles......I can neither build on them nor terraform them.

I second Coastie Aircrew on this... those tunnels tiles are quite unconvenients... I liked it better when they werent featured

Thank you for your reply, I had already tried to change the tunnel tile, I says i can build a road but it does not show up, it will not let me terraform the tile in any way, I think you will need to disable the tunnel tile for this to work. Sorry i took so long i was out of town for Thanksgiving.

@Coastie Aircrew Ah yes, Tunnels. Those were a feature I had only partially completed. They are meant to be impassable by units that are too large (unit rebalance is not a part of this mod though). Maybe you can turn the tunnel into barrens by building a road over it so you can then make a city? If not, i'll patch that change in (unless you have a better suggestion)

@Luthdraco Thats very generous ^^

OK I tested after the quick fix, and indeed you can now cast Restore Ocean Floor directly on the rapids and it becomes normal water. Terraforming spells can only be cast on your domain, so if you want to alter a rapids, build a fortress nearby. From the start of the game it goes like this:

1) Research basic seafaring (3 turns early game);
2) Research terraforming (7 turns early game);
3) 1 City with builders guilds (2-3 turns early game)
4) Make a builder
5) Move to spot next to rapids
6) Build a fortress to expand domain there
7) Cast Restore Ocean Floor on a rapids tile whitin domain
8) Build the bridge :-D

All in all it's quite a long process, but I think it is fine because at the start of the game there's no rushing to build one anyways. I've left a positive rating and gave an award. Thank you for your work and time on the mod.

I love the work you have done, but a new problem has developed, in the undergound any dirt that is dug by my builder become tunnel tiles and cannot be built upon (tower, City) but can be traveled. (Human Race Builder) I understand if you cannot get to this for a while, I have turned off the mod for now but would love to have it back. Thank you for your work.

@Luthdraco did a quick fix. now you can directly turn rapids into water via Lower Ocean Floor. Couldn't test it though bc in my tests I never got Rapids to show up. Let me know if it works ^^

@Luthdraco No that's not intended but an interesting find for sure :) In order to build a bridge on a tile two conditions must be met: 1)the tile allows bridges 2)the builder can walk on that tile. My mod makes rapids allow bridges, but since the builder still can't walk on them, it still fails. Not sure how I overlooked this until now :D
