Were expedition rewards bugged (in a good way) this week?

Did first expedition this morning and immediately retired it, shocked to get two champs in the epic capsule.

Then did second expedition, with a leftover token, retired, and got another champion! Something felt off about the whole thing so I rolled another expedition with shards, even though I I doing that with current reward structure, and sure enough, I got ANOTHER champion.

Either 4 champions over 3 expeditions is some weird luck, or rewards were boosted or something this morning. Anyone have similar experience?
