I am also having this issue. Here are the details:
we just, in the last hour, upgraded from spigot 1.15.2 to paper 1.16.1
we have never, ever, used any snapshots - either 1.15.x snapshots or 1.16 snapshots of any server version
we reset world_the_nether and world_the_end but we can NOT reset world
we run multiverse and multiverse portals. All the various worlds created via multiverse and linked via multiverse portals are fine, and the portals are working fine
we deleted all of our nether portals before the upgrade and have not recreated them
We removed all of our coreprotect regions before updating the plugins.
We are getting all the same no key position_predicate in MapLike that everyone else is reporting, however we haven't had any lag as yet and we haven't had any users kicked off.
I noticed in the comments that one of the devs thinks this is due to a snapshot being run on the world before, but as we have never run a snapshot, that can't be the cause.
