Yep mine broke again, and I cannot get it to go away. I do notice that every char I have with no issue are ones that have the rocket boost with a redish selected fav that you cannot click. All the ones that I have cleared with clear all fav are now broken. I have deleted the entire settings folder and let it recreate but it still knows where my buttons are on a char so it must be saved server side along with this other setting that it jacked up.

I had this bug but resolved it. Two of my chars activated rocket boost when I log on the other 8 or so did not. I logged on one that had the issue, and cleared all my fav mounts and removed the random mount from bar then logged out. Logged back in and no auto rocket boost. This one char fixed all my char that had the issue. Set all my fav mounts and added the random mount back to bar and all my chars were still fixed. It seems the server gets some thing saved server side cross linked maybe.
