How do you delete all of your custom unit designs off Steam for good?

Look in the following directory:

Documents/My Games/Legendary Heroes/Units

Then delete all the .xml files with the names you want gone.

I did that and they all came back.  That's why I asked how you delete for good?!

There is a way of removing ALL information from the steam cloud (a reset if you will). I don't know if it works and I haven't tried it myself. But this information can be found on the steam forums. As to the specific game, I've not a clue. But I suspect you can turn off steam cloud.

Yeah, sorry. The "for good" part doesn't register for me since I always have cloud off. My mistake.

Right click your game in steam library, go to properties, on the 'updates' tab untick the steam cloud sync, then delete the units and races you don't want from your documents folder.

But how do you delete them from the cloud?

I don't know if this works, but here is a thread on the steam forums...

FYI: Legendary Heroes is number 228260

Especially for the beta, where old unit/sovereign designs can become invalid between beta drops, this needs to be made easy for the testers.
