Bug? using block on a jellyfish... then having it die to poison while block is active = cannot run/attack/use active combat skills when the next 2 jellyfish spawn (those buttons all blacked out, INCLUDING block). happened to me twice in a row, so i could perform no action but wait until they slowly killed me. It was as just not allowing me to unblock... Items were still usable however, so i was able to use a burn scroll to escape the first time.
