When clicking on game icons for group games shown here, it will always link to a error 400 bad request.
They all seem to lead to the same broken link that all miss a placeid value: is https://www.roblox.com/games/refer?PlaceId={placeId}&PageType=GroupDetail&LocalTimestamp={localTimestamp}

Was just about to submit a bug report and saw it here.
Can confirm the same thing is happening on a clean install of Chrome with no extensions.
I am also experiencing this bug, please look in to this.
Bump. This issue is quite critical for games like roleplays who reply on groups to function.
We’ve rolled out a fix for this bug, can you verify that the links are working correctly now?
All fixed. Thank you very much.
