Invalid target text

[Hipolyte]

Hello all,

Recently every now and then I am getting a message invalid target on my screen and text. The frequency I don't think is set.
It is as if I am pressing a skill without having target. If I am on improved balance ( I am playing SM ) it uses WoH which does not require target.
I haven't played any other character recently so I am not sure if it will do it to other classes.
Has anyone encountered such an issue and if yes how they fixed it?

Thank you in advance.

Some changes are necessary when you move it to another location like slope 3
