The Dynamic Campaign that was in TF Mod 4.3 is missing in v4.5 and they are looking for the creator of this campaign. He might be here on SimHQ, hopefully.
As the packaged campaign was lifted entirely from the the campaign by the enlightened Florist. I'm presuming that the campaign can be re added to Blitz manually like it was before 4.3.
I still have a copy of the original if anyone needs it.
