Love the electric overhaul mod. It unfortunately doesn't support yet Subsurface, so any connection to underground is not possible. Any chance to get a support for this?

This is the mod: https://mods.factorio.com/mod/Subsurface?from=search

Yes, I would think this is can be done. I will work on it.

Version 1.18.0 has been uploaded, providing improved support for Subsurface... improved as in, it should actually work. :D

Thank you very much for reporting this issue, greatly appreciated!

Oh man you're really awesome. Thank you for looking into this and adding support. It's so much fun having this mod in my current run and seeing the wide support for other mods is just fantastic. Thank you again.
