        event.processed = true;
        //Even though this isn't required as we're interfacing with it by reference. Just for good measure
        this.events.set(event.id, event);
        this.eventEmitter.emit(EVENTS_UPDATED, event);
    }
Sometimes, events might stop being relevant due to external circumstances
In these situations, this can be called to set them processed without an interaction
