Me and my friends seem to have two recurring problems with mods. One, our ACU is invisible. Two, upgrading a building will spawn another building directly on top of the one that we upgraded, instead of replacing the building. For example, upgrading a T1 land factory will make both a T1 and T2 land factory on top of each other. Same with mass extractors, or other buildings. Made sure to get updated versions of mods not just from the vault, but some mods are from the vault. Could be missing something, easily. What's strange is a few years ago we ran the same mods (since reinstalling the game showed what mods we had) but they weren't compatible anymore. Of course, this is due to the game updating, and mods not updating back. It's perfectly fine.
Here is the list of mods and their exact version numbers-
4th Dimension 2.12 V2 from the vault
Experimental Wars V44 from the vault
Total Mayhem V1.33 for all game versions (From forum)
Sorian A.I. V2.12
Thank you for your time, it's highly appreciated!
