Ahw, good to know, just refreshed again and everything was normal without getting more Stamina. That's good, last 4 Gather's had no Stamina remove, too. I just saw the post from Shadowfae, then I pressed F5 and had full Stamina again. Thought it will work everytime when u refresh the game. Since his post mentioned it, it happens more than one time.. I didn't want to try it out once more, cuz it felt pretty lame to me. That what have been a game breaking bug. ~ I would've lost a huge amount of moral, if it was abusable that easy without punishment.
I had like 197 Stamina when i should have 50+ By Gathering, It was to much Stamina (over max) with it and I lost like 100++ stamina.
i tried to refresh instant after this some times, and nothing happend, i used my energy and went to bed. had nearly full energy when i was there again, i thought this was a bit much for my little rest. guess there was something wrong already with it. well then i used some stamina and pressed f5 and had 400+ stamina again. If u add or take it away i was never under Zero with it - but 1 time over.
edit2: I tried to refresh some more times.. always 74 energy, and i wont regenrate over time.. if i keep constantly refreshing, If it's under 1 Minute, it will be +1,xx Minute when i refresh.
