Bug/Issue AI Townspeople Glitch (Nintendo Switch)

Well, I thought the animals were weird enough the NCP's can now phase through bushes. I was giving one of the NCP's an ice cream to raise them to 10 hearts and now they are phasing through the bush. I am not for sure if that was happening before I came when I loaded up the town map when walking to it and they start being all funky. Usually, the NCP's will go around things like (bushes, trees, and stumps) but what was different this time?
