Thanks so much for responding quickly to the community on this matter!
I was just in the middle of a run and tried looking for my “Tip of the Iceberg II” challenge to track how I’ve been doing, was surprised I couldn’t see it but noticed the new ??? challenges as you’ve previously mentioned above.
Thought I’d check Reddit to see if anyone was speaking about it and a Community Manager is quickly dealing with the subject which is great to see - I can definitely see the point in choosing to reset and try to fix it now rather than wait for a fix that wouldn’t come into cert until much later in the event.
Please keep us posted on any information BioWare has on how they’ll reimburse players for lost progress! Perhaps these Tip of the Iceberg challenges could pull data from challenges like Fall Harvest which tracks Outlaws Defeated or something of the Trial - Bronze / Silver / Gold Flyer challenges to roughly count towards completing 40 races etc?
