So since BETA the bug has been that often right after an action, casting a spell simply does not work. Instead of casting the demigod is stuck until a right-click command is issued. This happens VERY frequently and often screws up the game when instead of healing/saving a partner, you stand there and the partner dies, or instead of finishing off a demigod you stand there and he escapes.
Since this is such a major gameplay killer and has been around since beta... I am assuming this is a critical bug. Are you guys working on this? When can we expect a fix?
