[1.15.2] Weird issues with syncing data to the client

[Novârch]

I've created a custom entity that has a player as it's master, it's important to me to have this data on both sides for performing certain actions through packets, so I implement IEntityAdditionalSpawnData on it and write the master's entityID as an int and read it back on the client. This has worked perfectly for the last 17 entities I've made, but for some reason isn't working for the last one I made, this makes no sense as all of the entities inherit from a super class that calls the read and write methods, none of the child classes even override the methods. The debug.log I get can be found here, the entity's code here and the superclass that calls the read and write methods here.

From a quick glance, I would suggest checking if the master is null.

I check if it's null before writing, where else should I check?

You should try logging whether the value is null.

Currently, if the master is null, your write method wouldn’t do anything. I am suspecting that the master was never assigned (by accident).

Just tried that, doesn't log anything, it isn't null and it most likely can't be null because in the two places that I call World#addEntity to add the entity the master is always set, and the entity is immediately killed if the master is null, as seen in this line.
