Interesting. Ants communicate by smell (essentially), so much so that a live ant which is coated in the “I’m dead” compound will be repeatedly carried to the dead pile regardless of how many times that ant walks away from it.
So, something in Trix must include a compound that those ants identify as “Dead pile goes here”, and everyone thought someone else moved the dead pile lol
Providing something that is broken is very different from not providing it at all.
