I have completed well above 25 heroic events since triumphs launched on all three of my characters, my count still remains at 20/25. Please help.
Greetings! Thank you for your report. It appears that the bounty is character-specific only, so you may have completed 20 on your Warlock but your Titan won't show that number. The best solution is just to pick a specific character to complete this bounty. Let me know if you have any questions.
Have you tried doing one to see if the counter will up???
