Not sure if it's just me, but all of the Monster and Magic Items large images for Homebrew and Official content, are showing a broken link.

For example, the Dolgrim (https://www.dndbeyond.com/monsters/487585-dolgrim) has this link to it's image: https://www.dndbeyond.com/avatars/thumbnails/7725/608/1000/1000/637091619688542557.png

It shows as broken and opening the link in a new tab shows:

<Error>
<Code>RequestHeaderSectionTooLarge</Code>
<Message>Your request header section exceeds the maximum allowed size.</Message>
<MaxSizeAllowed>8192</MaxSizeAllowed>
<RequestId>8YV4TDC8QFADSF4W</RequestId>
<HostId>VkZVqPEf3Gbjqrikcb1CyWLAVLqxEM/4cHIzSiiVBIKn4jSaIMyhRpHNYqSupopuPWiLacI4PiM=</HostId>
</Error>

I will note that if you open the ERFTLW book, the statblock image works fine: https://www.dndbeyond.com/avatars/7725/609/637091619689636245.png

And 10 minutes later it appears to be working again.

The "request header too large" issue is related to D&D Beyond's use of tracking cookies and it can happen seemingly randomly whenever you use the site a lot. Clearing cookies and local storage for dndbeyond.com and logging in again usually fixes it for me.

 Had to come back here because I'd forgotten which cookie got to big.  Simply deleting the Ratings cookie has fixed it though, without forcing me to log everything out.

Thanks again.

Additionally, blocking third party cookies helps too.  Apparently the `pintrest` cookie is huge, so Ratings plus that together became too large.  I'd still love to know why they need a 2kb cookie for their own site though.
