Direct Selection Tool on Control Handles Doesn't Work Properly After Puppet Warp
Normally, you can adjust a single control handle of an anchor point with the Direct Selection tool without affecting the other control handle. But after you perform a Puppet Warp on a shape, this is no longer the case. Using the Direct Selection tool on a control handle affects both handles simultaneously. In order to reproduce this bug, the object you're working on may have to be a group of objects. Here is a video of the problem: https://youtu.be/qZoJOQb0seI
