Missing maps for custom games

[Ezekiel the dragon]

Hey, I have this very weird issue, some of the maps from my game went missing including helix which was my favourite. I tried deleting data files and verifying through steam, and completely reinstalling but they are still not there. I have the 1.8.0 complete collection on steam.

Helix is a modded map so I would guess all the maps you are missing are modded ones. You might be able to find them in the modding sub-forum and reinstall them.
