Luke, I downloaded 0.31 and looked at the .zip file before installing and there are two things IMO that you should change:
1) Don't include any of the original files on the mod. They aren't necessary since they are already present when you install OXC and it can be considered copyright breach.
2) If you want to change any of the original files, use a different filename than the original. This is important for two reasons: makes your mod more friendly towards other mods, since they might also need to use those original files and might not like your modifications; doesn't force m (and other players) to have to replace the original files if I install it and later I want to remove it to play vanilla.
I don't remember if I asked you before, but I currently want to add new Alien Base terrains to the Terrain Pack and yours is included if you give me permission. 
Valid arguments but:
In every MCDset i create some parts from the original file is included, so if they really want to push copyright i am stuffed anyway. All i can claim is Fair use.
The U_Base file is only a FIXED version from the strategy core site, i did included it just to update peoples ( like me) who still run off the old Dos version. That being said, its a valid point, next release i will add something to the Readme about it ( if i didnt already, cant remember).
Yes you ( and anyone else) has permission to reuse any of my work, as i didn't create every little detail of it ( that copyright issue again) so it wouldn't be fair for me to say don't use it.
Alderon.... Can you upload a FIX i wont have time to look until the weekend otherwise.
Solarius, Medium maybe ( need to check how many MCD required) Large... Not as hopeful. I have a feeling there is still a issue in Mapview with MCD limits even though OXC doesn't have it....
