Hello!
Today I finished all of my Strong Approaching and after that wanted to help one of my group's lower lvl players with his SA easy runs, however, the game told me I have too little stamina to enter. Unfortunately, I don't even have any stamina potions and have only 5 stamina at the moment, nevertheless from my understanding it shouldn't be like this. Today the same happened to one other girl from my server, but as far as I know SA did not eat up any of her stamina after she used a small stamina potion and went in with 12 stamina. I therefore think this might be a bug. :)
Hope you guys look into this/explain why this might have happened. Cheers. :)
