Nice nest! And yeah that's the issue with setups with connection systems like these, ants hiding in the connectors and casualties when adding or changing setups Love to see the communication between ants with a nest move, like the "all clear signal" and everything. Usually it takes a bit before they deem a nest suitable and save to move in, so all and all this was a very fast move. You can see they find the nest a bit scary at the beginning first, hiding in the tunnel haha. The tunnel is easier for them to maintain the humidity, thats why they will keep the larvae and eggs there
