The second one is probably an error, as it means some kind of failure in our application of bucket types to CRDTs. The first one is tough to decide…it will happen if CRDT is serialized incorrectly or corrupt, but it will also happen if a users data as a binary _happens_ to start with the series of bytes that a CRDT does. It would be a big  coincidence I guess, but since EQC found a few…I dunno…pick one, you're the reviewer :smile:
