Since update 1.1 its not possible to open default Reforger Prefabs in Workbench!

The Edit button is disabled.

So, if you just like to take a look into the original one, to see how its done, you always need to create a Copy to your mod, then open it, get your info and delete it again!

This is a verry bad Workflow and much wors then before! Please go back to V1.0 where we always can open original Prefabs.
