Same game as the previous report. I unlocked the Wellness bonus that let's me play my Capitol planet for free. The planets that were played the previous turn were: the anomalous planet shown here, the Capitol planet, and one other planet.
The anomalous planet partially blocks clicking the otherwise-functioning planet behind it.
[edit] I played another turn, and the anomalous planet went into the discard pile. The game seems to have returned to normal functionality. [/edit]
