Enzojz? Why are underground station from webdisk and complex station from steam incompatible?
They are sometimes not compatible since
1. My mods shared the same lib
2. One mods will overwrite other's lib if they are on the same filename
3. I put only stable version here, Steam versions are more frequently updated since it's much easier to receive feedback there, it's also much easier to release mods there. (Here I need to pack the zip and copy-paste mod information)
4. I think if you have access to steam you can have all steam versions, it's not necessary to mix two.
If you have such problem please remove the version from here and use steam, it will resolve all.
