Firstly i found this albeit this is starwars looks like the same issue
So the issue is this, If you have an npc spawner with a sidekick definition and then update the definition and spawn a new npc the sidekick does not change from the default definition in the device. If you change them 1 by 1 in the device like set the device as def 1 then 2 it somehow works its hard to explain what’s happening fully as i dnt know myself
Please select what you are reporting on:

Steps to Reproduce
Place an npc spawner and create 2 definitions i use the cat and dog
set the spawner as 1 then in verse update the definition and spawn at player location
Expected Result
It should work every time
Observed Result
Something is broken but its so weird that sometimes if you change between a few then update/spawn 3+ sidekicks then it might work
