Yes, I nuked all the characters after the server update (that happened sometime in the night).
The official server is good for now. We're running tests on the test server and it's up and down.
As we are making changes to the client code without patching them out to everyone, the test server will be inconsistent (and I'm wiping the database very frequently).
The wipe was intentional. It was necessary because of a few things such as scavenged items with no counts and some recipes being available that shouldn't exist (we don't have a model or part for them).
I don't think I'll need to wipe characters until an update that is coming soon that includes a new terrain rendering syste.
