Hi guys, I know it's been mentioned before but since you've 'ajaxified' the approaching it allows me to see this problem differently.  So the energy bar.  Here's the deal, I have 5 engines, obviously to use the last jump I have to wait, but as I watch the energy bar fill up to 50, I click on it but it says I don't have enough energy to jump... then I continue to click and it keeps telling me in red text there isn't enough energy, but once it is at 65 I can finally jump.  Before, I would have just thought that the energy bar refresh isn't synced properly, though strangely enough once I did make that last jump I am indeed left with 15 energy which is correct.  Before, if you try and jump when energy bar appears to have the correct power, it will say not enough energy and each page refresh brings the bar back to an arbitrary amount much less than you would expect, and each page refresh after will keep returning to this arbitrary amount for quite some time.  It's pretty annoying
