The update to my FM mod is now ready for download, pending approval from the moderators.
FM 3.1 corrects the "craft invalid" error which prevented some friendly and enemy aircraft from properly loading and appearing during some campaign missions. All aircraft currently available in HITR should now appear in your campaign as originally designed.
The update also adds upgraded engine version of the Sopwith Pup, Sopwith Tripe, Spad VII, and Spad XIII aircraft.
For instructions on how to install and use this update, including information about the alternative airplane versions, please see the full readme included in the HPW FM and EW Campaign Mod zip file.
Please direct any questions or comments about the installation or use of this mod in this thread, not the old 3.0 FM thread. As always, feedback about the mod is appreciated. Finally, thanks again to OBD Software for their help and support in the development of this and all other mods.
Cheers!
