Unable to open Feats page in 5e Compendium

I've had troubles opening the 5e Feats page ever since I picked up most of the books in the compendium. In the rare event that it does load, it's extremely slow to open. I'm not certain if it's an issue with loading too many or something, but 95% of my attempts to get into that page, and only that page, result in Cloudfare or Roll20 errors.

Is this inside or outside of the game? I.e. Compendium page or Compendium tab? NVM, I just tested. The page is returning a cloudflare error. You should report this with a  Help Center Request .

In the meantime, I don't seem to see an issue with accessing the info in the in-game tab.

Thank you for the prompt reply, I've submitted a help center request.

I'm having an issue when you use charactermancer that at 4th level I can't select the feat options.

Charactermancer does not allow feat selection after first level. It's a known situation and in the documentation. The dev position is that it is impossible at this point to alter the sheet to mathematically account for the alterations the feat would make to characteristics, hit and damage rolls, etc. But this does not explain why you can still do it at first level, and why it can't simply paste the text for you with a disclaimer to make any needed adjustment yourself. The accepted method is to ignore the ASI if you want to take a feat; Characetrmancer won't stop you from saving changes. Then drag and drop the feat onto your sheet from the Compendium tab.
