This might apply to pallys as well. I know that when I, or anyone else I have talked to that is a SK, sit down or swim we get spammed with messages saying "You cannot do that while sitting." or "The water is too deep for you to do that." Just letting you know that SoE has acknowledged this as a bug and will be fixing it asap. It is assumed to be a problem with our mounts. Nothing you do, aside from filtering it out, will get rid of it for now.
