Land mines on a raptor disable all the combat skills

[Urud.4925]

In Dredgehaunt Cliffs (around Dociu Excavation) whenever you step on a land mine with the raptor, you won't be able to use your skills anymore, when you unmount. You have to go back to the character selection menu and log-in again.

It's absolutely a minor bug (sometimes it also happens when you are transformed into a sylvari, in Caledon), but I reported it just in case it's easy to solve it :)
