I also posted this in the bugs section, since I don't know which it belonged in.
Okay, I bought and used one of the 1 hour skill bonuses. I forgot I used it, and tried to use it again. Of course, when nothing happened, I went into the info. It said 2 things that directly contadict eachother: CONSUMED ON USE and 0/1 charges. That means that the item can be used but remains in the inventory.
My problem is that these items can be used and THEN sold. So people who end up buying these will be essentially wasting potentially millions of EC on useless junk.
