Item Cool-down

I find it harder to use items now even though the new update claimed to have put a cool-down timer if you are trying to use two items at the same time. This is NOT the case because when I try to use only one item, (no combo and haven't used a item for a long enough time), I have to wait a second to use it which is EXTREMELY ANNOYING in those critical moments. Fix this so that the cool-down timer only triggers after you used one item not to long ago.

One example was when I was low on health and tried to use a health potion. But when I tried to use it, my character did not consume it. This led to me being confused mid-way of a fight and sometimes resulted in me dying.
