Chanber ranks have reverted to previous levels and I can't work out how to report

It appears all the chambers that made it to era's vanguard 1 have been reverted to era's vanguard 2 - doesn't seem like a massive issue, except that rank up challenge is essentially a paywall. Hosting celebrations requires spending gold to get tickets, and i can't work out how to send a bug report on the discord (i went to the official channel and it says to message the bot, but i don't know how to do that) so I'm a bit stuck. My partner did a bug report on the website, but i figure more reports are better so if anyone can help I'd appreciate it 😅

Also lowkey if you're in one of the affected chambers and didn't notice, now you know. Included his bp rank in the screenshots, in case anyone thinks i just posted the pictures out of order, so you can see that his bp went up and chamber rank went backwards. Thanks in advance for assistance, appreciated
