I don't know what your "game folder" is... but please DO NOT use anything from OXC... it will create conflicts and crashes.
The mod comes with a compatible OXCE+ installation included.
Just extract the mod on your desktop, copy original TFTD data files and run... OXC is not required, nor desired.
OXCE+ comes with the mod... you can upgrade it if you want, but don't have to.
And new bugs:
Triton trying to engange a USO, what shouldn`t happen. Can`t leave the interception-window.
This is not a bug... it's a new feature
You have been attacked by a UFO hunter-killer... UFOs can now also attack your ships...
