I purchased just one Rush Order for 1kp, and the very next price is 5kp? I will check this again after rollover and get a screenshot if it is weird again, since I can't really prove that I've only purchased one so far today.
here's some images - i purchased the first for 1kp, used it, and then the second one was 5kp. I even bought it to see if it was just a visual bug, but it did take the full 5kp. also wow sorry these are massive??
