I think they made a mistake when Scott Tennorman was still butt-hurt in 201

[Musou Miyata]

So we know Scott and Cartman had a falling out in season 5, Scott did some things, Cartman did some things, it got pretty nasty.
Then in season 9 when Cartman thought he was a ghost he decided to make everything right and Scott forgave him. It's over, Scott's haappy, Cartman's happy.
So why was Scott butt-hurt in season 14? There had been no interaction between him and Cartman since season 9.

Cartman did want to make things right again, so he handed out baskets to everyone he wronged. Scott was at the cemetery sobbing over his parents' deaths when Cartman and Butters gave him a basket.

This doesn't mean Scott forgave him. It means he appreciated the thought, but probably thought about it later and figured that it's f*cked up that the boy who had his parents killed and made into chili all of a sudden gives him a basket? What kind of sick f*ck does that? So it makes sense that Scott is still butthurt in "201."

The other thing that's wrong in that scene is the graves. If Scott's parents were made into chili, there would be no bones to bury, so Scott shouldn't have any graves to visit.
