Guild Wars 2

Well, the pink box had writing on it telling me to report it as a bug if I see it, so yeah.

Simply put, it seems to only happen when swapping from Jalis/Dwarf to Ventari/Centaur. Tried other swaps and wasn’t able to replicate, so seems to be linked just to this one

Confirming the issue, with a bit more data :
The box appear whenever you switch to Ventari (reproduced both with Jalis=>Ventari and Mallyx=>Ventari)
It seems that it is a placeholder for a missing Ventari invocation animation.
