It happened a few times, in the evenings.
I caught a three pikos, went to the city (to the area around my house) and dropped them near by tea trees (dragging from my inventory to the ground). When one of them woke up, and then, immediately after this, the second one - the game crashed.
At the same time, when i dropped only one orange piko on the ground, and it's woke up - everything was perfectly fine.
Maybe this text will help (first crash):
