I was trying to energize just one pet specifically before I landed on the mirror world when something popped up. Well, I should say nothing popped up! My energy drink stayed in my inventory and my pet's energy bar remained untouched. But there wasn't any kind of error message or anything of that sort.

The reason I was trying to energize my pet was because I had put them on a mission and only one of my pets needed energy to land on the mirror world. 

What happened was that my squad had already researched and was ready to land on the mirror world island, except for the one that went on the mission. So I tried to give them an energy drink instead of wasting a whole squad energy pack, but when I tried a blank screen showed up. I tried a few more times after that, but with the same result.

I understand the circumstances are very narrow, but I thought it might be worth bringing up.

Also my webbrowser is chrome version 33.0.1750.152 and I'm running a mac with os x 10.9.2 so my stuff is all up to date (if its relevant).

Thank you for reporting!

There's some script error if to judge by the screenshots. We'll try to fix this as soon as possible.

Sorry for the inconvenience.

Its fine! Thanks for listening!
