Hostile Mobs Won't Go Through Portals

[Munchkinnibbler]

Hi, a server I assist on is having an issue with nether portals in that passive mobs & items can pass through portals however hostile mobs just vanish.
The config is set up as follows:
bounceback: true
teleport_entities: true
send_no_destination_message: true
send_disabled_portal_message: true
worlds:
testing_world:
portalgoesto:
NETHER: testing_world_hell
testing_world_hell:
portalgoesto:
NETHER: testing_world
HermitVeterans:
portalgoesto:
NETHER: hermitveterans_netherworld
hermitveterans_netherworld:
portalgoesto:
NETHER: HermitVeterans
The server is running on Purpur 1171 (the latest and last 1.16.5 version) and so I believe it will be using a 1.16.5 version of multiverse portals. I've tried asking around but no solution has been found, is there anything that would fix it?

I feel like this relates to my issue as well: See #230
It would be nice if someone could try to resolve this issue :)

Indeed it would

#230 Does seem related to this only in 1.16.5 so to hazard a guess it's been there for a while.
