Thank you very much, I really appreciate that you warned me about these little details. I've already patched the 'str_you' thing, it should correctly show the english translation. And yes, it is where you are located in the map 😄.
As for using the mouse when you have no abilities, I've made it clearer when you have no abilities. A text sign will show up warning you when you have no abilities, and I have removed the usage of mana and sfx in the same situation.
