Credit Heists are indeed scheduled by us.

They are "random" insofar as we do not post the dates on the official forums.

Hiya Holotable Heroes,I'd like to provide clarification regarding Credit Heist and Droid Smuggling Events.Per posts made in the past (over a year ago) by our helpful devs , we initially sought to follow a cadence and window of time in which Credit Heists and Droid Smuggling events would launch.Going forward, know that we'll be working to better meet the needs of upcoming in-game events, Character releases, and so forth. Our schedule moving forward may not adhere to previous cadences, but don't fret, we'll continue to run them regularly!
