Reducing the frequency of thought bubbles was a change in the December update. I’m certain the change is appropriate in the majority of situations. However, the thought bubbles zois used to get while gathering informed me of the item gathered when it’s a known find. It was more engaging for me to see the zoi think about what they found than to go through their inventory frequently to see what they’ve gathered.
Can you please restore thought bubbles whenever a new collectible item is added to their inventory? 
Thanks!
