I don't know why it borks, so I need to dig around, which'll take awhile.
When I find motivation I will (I haven't been doing much work on SM mods for awhile).

any updates or is it done for

Nope, kinda forgot about it :)

Hello, is this mod working now?

eventually

Hi ChoGGi, do you plan to update this mod? I love to build spread out my bases all over the map and this mod was very useful to keep distanced despite that short. I enjoy all of your mods greatly and can't thank you enough that you (and a few other modders) made Surviving Mars so much better and bigger!

this is causing transport to lose resources when it goes through a tunnel on another level (higher ground)

Does not work properly.
Outputs are constantly changing pairing.
It often happens that a cluster of aqua extractors does not work due to a low load, although there is no water in the colony.

Just did a little more testing, and I can confirm the rovers do travel through the tunnels properly (only had some pathing problems with 2 safari rovers stuck entering and exiting the same two tunnels but I think that was just some pathing on my end), and that life support/ pipes do not work across the different tunnel networks.

I fiddled a bit to get them standalone, but the rovers don't use them for pathing then (other than manually), I'll have to dig through and figure out where they check whatever they're checking...

Thanks HoGrRo.

I tested the tunnels for the power and they didn't work. I'm not sure about air and water since since the only isolated section of my grid only required electricity. I didnt want to go removing piping everywhere, but my guess is its the same for piping as well.

Was anyone able to test this with electricity/air/water and so on? Curious to know if it will link separate "grids" into a single larger grid for resource sharing at different tunnel-connected sites.

Hopefully should be fixed now.

Mind uploading one of the saves?

uninstalled for now, cool idea but for reasons unknown on several of my saves vehicles path correctly as though the tunnels are interconnected but they fail to travel to any exit other than the original paired exit, causing the vehicle to stop it's task and sit idle at the tunnel entrance.

Yea, still gotta do sets. Might look into singles someday.

so do you still have to place a set of two?
or can you just place like 3

Hmmm, let me know if you find any bugs I guess?

THANK YOU SO MUCH!!!!!!!!!! if there is any way I can repay you tell me
