Planet was reserved, but no points were stockpiled. I don't know if this is a problem with the building itself or an interaction with the planet's passive ability to stay in hand when reserved.

[edit] On a related note, it's really hard to test if the buildings are working if I have to properly earn them every single game. Would it be possible to get a Debug Mode on the Production Panel that allows testers to build locked buildings for free? [/edit]
