@buhler86 Sure

@zai4z I can provide a list of mods if you want to look into

It occurs to me (over a month later.... I'll ignore it if you will) that I probably should mention that I do like this mod.
It's not anything ground braking and on most maps by the time you get it you've often worked around the problem, somewhat literally .
But when it is useful you're glad you had it. It's a bit like the D&D Mending cantrip, it doesn't sound like much but when you do need it you're very glad you have it and afterwards don't really want to be without it.

I've yet to try it on the Riverworld map, but I find myself looking forward to it.

@buhler86 My tunnels and VMP definitely work fine together, so yeah its another mod that doing it

Doesn't seem to work with the other mod's I'm running. Also the Kilimanjaro ability doesn't work either from the "various mod components". Dunno which mod it is clashing with, my guess it's workable mountains mod by Keukotis. I also adopted the "home of the Gods" pantheon so maybe to many mountain related actions.

Oh? I somewhat understand that. Either way it sounds better than what I tried to guess was the reason .

Seeing as more likely to see this I do have a quick(ish) question. Would it be possible to apply the Tunnels promotion that Workers get to Fishing boats?
Now, hear me out, hear me out! A curious side effect of having that promotion seems to be that Workers can now (while embarked) pass though ice, the mountains of the ocean. Which it seems the game takes literally.
I'm not asking if Fishing Boats could go up mountains . But it would be nice to access fishing spots that for most of the game were always just out of reach and let those boats go where larger ships fear to sail.

@Amanoob105 when loading into a game with existing tunnels on the map, the mod needs to reload to update graphics, and therefore it create a temporary save file to load from

An extra save file turned up called "Tunnels Autosave", which while I can't say for certain may be 'dated' to the turn I started building my first tunnel.
This isn't really a complaint and more of a "huh?". Is this a thing the mod now automatically does in case building tunnels crashes my game?

On an unrelated note, I'm also using the =Aquatic Resources= mod mentioned below and so far they seem to have been playing nicely together across more than one game. Also no idea why.

This mod does not seem to work with =Aquatic Resources=. No idea why.

Re: Workable Mountains
After a game re-launch (and reboot), both mods are working fine side by side.

Is this compatible with Workable Mountains by Keukotis (steam id 233614126)?

My workers gained the Tunneling promotion and were able to enter mountain tiles, start a tunnel construction, then add a railroad to it. However, the other units didn't update pathing, and the strategic view doesn't show a road through the mountains (it shows nothing).

thanks zai.... tried that and it didn't seem to work.
I'll double check and make sure I did it right.
worse case, we crack another beer and start a new map!

@Verb It isn't, but if you set the AffectsSavedGames Tag in the .modinfo file to 0, it might work

curious to know if its possible to get tunnels v2?
I accidentally upgraded and saves won't load
thanks in advance

@zai4z G.O.A.T.E.D

@LenC https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=3489014824

@Илюша Гантеля I haven't tested with CP, but it might break this

<Technology_FreePromotions>
<Row>
<TechType>TECH_DYNAMITE</UnitType>
<PromotionType>PROMOTION_TUNNELING</BuildType>
</Row>
</Technology_FreePromotions>

Honestly, CP is a shitshow so I wouldn't be surprised

some problem with game crash after researching dynamite. i'm playing with VP and CP. do i understand correctly that they are conflicts?

@zai4z Epic all the best ദ്ദി ( ᵔ ᗜ ᵔ )

@LenC Yes, it's currently in the works, maybe 2 weeks

Will you be making a Canal version? :D

@9R1N90V13J0 Can you give more information? Are you using an old version save?

Game crashes upon researching dynamite.

Thank you for updating! This is great work! :) :)

@Tasi The new version isn't compatible with old saves. In the new version, workers can enter mountain tiles upon unlocking dynamite

Just tried this new update and tunnel boring machine is gone and workers can not enter a mountain tile, hence the mod is now useless to work and it does not work

@독도는한국땅 Should be compatible in this new update

Oh, that's too bad. But thank you for your consideration in this matter. I'll just play your mod without MTL mod.

@독도는한국땅 Unfortunately due to the complexity of unit stacking I can't make it compatible

@洋葱骑士昆西 Thanks, this is patched now

hey, guy. I find a bug that I build a tunnel in a mountain where on the coast, and then my submarines can go under-ground by the tunnel. Could you fix it? Thx！

[MTL's Mountain's N' Unit Stacking]

I think this mod is not compatible with your mod. Tunnel machine can't move to the mountain tile.

If you state the mod causing conflict then I might actually be able to make it compatible

It doesn't work for other mods
