Bind Wisp can crash servers

[ZeekDaGeek]

MC Version: 1.19.2
Hexal version: 0.2.18
Hex Casting: 0.10.3

Attempting to spawn and bind a wisp keep causing the server to crash. I imagine the exact recreation steps don't matter too much, since it's probably a case of an unhandled null.

Edit: The reason I believe it's happening is not related to the fact that I'm using a Null iota, but the wisp that I summoning instantly despawns and I think by the time the bind wisp activates the wisp entity is null on the Java level because it disappeared.
