If you had problem to get an upgrade, please try it again.
My servers at Golgothica handle all the redeliveries/upgrades. However it seems that the region had some issues, because I was also unable to save any script.
Anyway, I ended up to restart the region. I think that it should be allright now, but if you get an error message, saying that there is a network issue etc, please IM me. Thank you.
