Supervisor told me my tool offsets were the problem, he was right

Been running a Haas VF-2 for about 2 years now. Kept getting these random finish pass issues, parts looking like a washboard. Thought it was the spindle or the material. My supervisor finally came over one day, looked at my offsets, and just said "you're chasing ghosts, check your tool height offsets against the presetter." Took me 20 minutes to compare all 12 tools. Three of them were off by 0.004 plus a couple were 0.002. My probe was dirty, that was the whole issue. Cleaned it, reset everything, parts came out glass smooth. Felt like an idiot. Has anyone else had a dirty probe throw off their whole setup for longer than they wanna admit?
