Anomalous coins do not expire and can be saved for the next event!

Events in the Temporal Anomaly have their own Markets with unusual goods. Tap on the Temporal Anomaly in the camp or on the blue notepad to open the Market tab. 

Anomalous coins can be obtained by completing tasks on the anomaly islands.

Some goods in the market will change after you buy them. This happens when the next event in the Temporal Anomaly begins.
