Ping Pong

Greetings, I'm new to this blog but relatively 'old' with Hanne Falkenberg.
I've make two mermaid jackets - the second using a Rowan yarn with exactly the same weight as that provided in the kit, I just picked out my own colors.
I'm currently completing the Ping Pong jacket, sans bobbles. I loved the shape of the jacket, but the bobbles are huge, and after testing them on a swatch, I decided that one wouldn't want to sit down wearing a garment with that many lumps on it. (And the possibility of looking something like a colorful Michelin Man, did not appeal.)
Regarding the HF patterns, I've often wondered whether there is a site that lists corrections to pattern errors - it has there never been such a case?
