Season 33 is now life!
According to the launcher at least.
They have set up a script to end/start seasons for the next 10 years probably but it doesn’t cover forum posts (“what forum haha” I guess).
If you’re US you can still clean up your stuff, Asia and EU have ended.
Towards the bottom of the post in the launcher with the same name as this thread it states:
Your Journey Begins…
Exclusive rewards and challenging enemies await you, but they won’t last forever! The cultists will appear on December 31 at 4 p.m. PST, and the portal opens January 3 at the same hour. Both parts of the event end January 31 at 4 p.m. PST.
This sounds like season 33 was supposed to last until Jan 31st. Well at least the event was supposed to last until then.
