Since this afternoon, it seems to be a problem in mana regeneration of characters... Yul Archers, Othell and Feoh, but also Iss and Aeore seem to be blocked in mana regenerating passive skills when hunting mobs in party full. Trying different situations, with one or two Yul, one or two Feoh and the issue still remains. As it was not the same situation we encountered in hunting yesterday, could you please check if there's any problem about this? Thank you.
