Just to clarify, this will effectively invalidate any previously saved multicast groups?

We only have 1 in the testnet that we created yesterday (mg01), so it's not unreasonable to do, just want to make sure I understand the side effects of the change.

I think so, @juan-malbeclabs can you answer this question? I suppose this fix will indeed invalidate existing mcast groups, so we need to think about whether including this change effectively means redeploying on testnet.
