Observed behaviour

On my MineColonies Modpack, several Iron's Spells Mobs will cause the server/game to crash.
Mainly for some Mobs that 'summon'. Archevoker, Necromancer, Dead King are all examples of mobs that cause crashes when they try to 'summon' something. Cryomancer also crashes when they try to summon their polar bears.
Specifically, it is an Entity Ticking error/crash.

This isn't just a Server Crash. But even when you go into Singleplayer, they still cause crashes.ia

Expected behaviour

For them to summon their 'entities' without crashing.

Steps to reproduce

1. Play a 1.21.1 Modpack with Minecolonies and Iron's Spells added(Preferably 'Twisted Towns' as that is the Modpack that we are using when we get the crashes).
2. Have one of the listed Mobs get spawned and wait for them to 'summon' something.
3. Crash.

Crashlog Check

• I understand if this is a crashbug and I did not attach a crashlog, this will not be handled

Fabric Check

• I understand if I am using Farbic APIs or Connector, this will not be handled

looks like an issue with "spell_colonies" being outdated from the summon rework, this must be fixed by them

Alright, thanks for replying.
