Was trying to contribute to Shuddering Hollow event on Siren Isle. Sat at the page to contribute for several minutes. Event goes to a status where I can contribute. I contribute a couple times, it gets to 7%, I stop, complete the quest to contribute once.
Get the quest to contribute 10 times, but when I go back Shuddering Hollow is marked as “event complete”. With progress bar still reading 7%.
Looks like more than just the Shuddering Hollow boss is bugged.
