Is there a way to wipe all designs AND templates? Or to reset steam cloud sync? Or to force the steam cloud to use your current local folder as the 'latest'?

In-game ship deletion seems to be working fine and syncing properly in .97, but I seem to have a legacy template (not ship) from .95 that I can't manually delete from the designs folder when steam cloud sync is on. I have tried turning off steam cloud sync, then deleting the template and playing which seems to be ok as it will not pull the template up, but does this mean I can never play with steam cloud sync on?

Clicking on the old template from the designer when I try to choose a hull causes the game to crash. The template is based on the prototype scout which I named US1, but it is still named Prototype Scout M1 in the Designs folder. I noticed the .objgfxcfg file is missing (not sure if its not needed if its template?)
