This has happend to me a few times now, only on sch but not on smn (though I dont' play smn as much). I'll use aetherflow to get mp/charges, and it goes on cool down, but no mp or charges are restored. I feel like it seems to happen more when I'm trying to do things in a hurry (maybe its being clipped with starting a cast?), but it happens so randomly I've no idea how to test this.

Has anyone else noticed similar issues with SCH? Any smn players know if it happens to them too? Any known work around?

Has happened since patch.
