I can't seam to get this to work with 14w10b.

I am still getting the same error: Name and ID cannot both be blank.

Is there a new server property that needs to be added to existing servers?

Dakota Brink 2014-03-06T18:14:12Z

Can we re-open this please?

kumasasa 2014-03-06T19:24:10Z

Reopened & Confirmed.

kumasasa 2014-03-06T19:32:35Z

Exception occurs until server is started with

online-mode=true

After that, the server can be started again with

online-mode=false

Tmk 2014-03-08T13:30:14Z

14w10c fixed it for me. Thanks
