Smooth Anchor Bug
Shapes created with the Blob brush, and then simplified with the simplify path tool are creating some weird smooth anchors that look like corner anchors based on the handle locations and line angles exiting the anchor. But when you grab a handle, they snap together or straight, changing the curve shape in an unintended and undesirable way without warning. Very frustration and time consuming to correct.
Yeah, Adobe constantly trains us to expect broken behavior, because AI is bugged as summer garden.
If this is expected while broken, then change it to unexpected while fixed.
Same here, chatted with Adobe. They told me this is the programs expected behaviour. :D
