It acted the exact same way before so "changing it back" will not fix this issue. If you are a helper on a post that will automatically invalidate the link (see post #7 in this thread). These "helpers" get re-synced with each new person who joins through the feed post but as you can see this is far from a perfect solution. We have to balance usability with overall performance but there could be more changes coming in the future to address this. You can still re-join this players Elites but going to their Profile but I completely understand this is not the desired workflow.
