I don't have any proof of this but it happened a couple of times to me and not sure if this is a bug or now but...
When i use multiple sometimes some specific sub-powers seemingly at random stop functioning properly
The latest example is conditions never being true even tho the resource requirement for it is the amount it needs to pass the condition check
The only way to fix it from my point of view is to separate them in different JSON files without using multiple

Same here
