backchamfer op wrong after update

hello guys, I'm having a weird problem that I believe its a bug, this op was working just fine a couple of days ago and yesterday when I made some changes to the design and regen the toolpaths it got messed up. it's a simple contour with a 45deg 6mm dovetail mill to make a backchanfer but it's going WAY outside, I didn't noticed until I remachined the part and at the end the part wasn't chamfered. I didn't even checked the sim because I didn't changed the design on that profile so if it was working fine I assumed it was still good... 
I tried to delete and redo the operation and still doesn't do the correct offset.

I have a similar op on another setup with similar parts arrangement (lids for the other parts) and its fine BUT if I regenerate the toolpath it gets wrong too so it's definitely a bug...
