Using version 1.4-30. Currently receiving this error. I'm not sure if it's an issue with the addon itself or a conflict with another addon. I honestly do not think it would be a conflict with another addon since it had been working fine until today.

Currently recieved this error. Skada's window will not show nor will the mini map button.
