"Could not pass event PortalCreateEvent to WorldGuard"

[TheosisOfficial]

Describe the bug
When passing an entity that isn't a player into a Nether portal that causes another Nether portal in a different world to be created, this exception is thrown.

Immediately afterwards, this exception is also thrown, however this happens regardless of whether or not PortalCreateEvent is called - it happens any time an entity that isn't a player passes through a portal.

I'm assuming these exceptions are related since they both seem to involve a null entity, but this is fairly out of my depth. This bug doesn't appear to break anything in-game, it just causes these two exceptions. Regardless though, it would be nice if they could be fixed. :)

The bug is happening on what I believe to be the latest release of Hyperverse (https://discord.com/channels/766366162388123678/766373499374927912/852894048590495744).
