Looking at the code I can't see any reason why that could happen. The method is triggered by an event, that passes through an array reference. The method itself tries to add an element to that array. I don't have a clue why that could cause an illegal offset type 🤷

@JasonMortonNZ let us know if this is resolved by the translations fix and we can close this.
