Right so now we have the Buy energy side, which says

Post an offer to buy: x Crowns for 100 CE.

Reading it through, it sounds like you're buying crowns, not energy. Also, at first I thought you couldn't place bids for multiple hundreds of energy at a time without doing math. You can, but it still says, for example, 4000 crowns for 400 energy, when what you're getting is 400 energy at 4000 crowns per 100 energy.

The Sell Energy side is equally confusing reading:

Post an offer to sell: x Crowns for 100 CE.

When I read it the way it's shown it seems like it should be meant to sell crowns, not energy. I only know it means the opposite because it says "My Offers to Sell Energy" underneath...and because I know that's what was on that side before the changes were made.

There also seems to be a bug associated with the change where if you try to sell energy immediately using the Need Crowns? button, you only get a rate of 100 crowns/ 100 energy.
