Is anyone else having difficulty finding lambs?

My side account is one day ahead of my main in the event. With my side account I found the lambs in one go, no energy boost needed, very simple. However, in my main I haven’t found any in 2-3 days of playing. I have used multiple energy boosts just today and still nothing.

I don’t know if maybe it’s a bug that after the first day when the lamb event was first available the lambs just stopped appearing? I haven’t had the mask on and I’ve been to three different exploring levels trying to find them but alas to no avail.

I just retired my previous king and I’ve been leveling up my current queen so I’ve had many energy boosts and still not a thing to show for it. I’m just a bit confused.
