Bug - Cannot use any skill / until I speak to a NPC or restart game

Playing rogue char on PC, I’ve had this bug twice now :

  • I’m fighting/questing then I cannot use any skill anymore (including evade) : the skills icons are “pressed” when I use the key/mouse binds but the skill does not happen (and is not on cooldown)
  • I cannot teleport to town (either using T key bind nor the map)
  • I can still drink health potions and move
  • Speaking to a NPC makes the skills working again

I’ve experienced this twice already. Quite annoying!
