Stop trusting your tool offsets after a crash, I learned the hard way last shift

I used to just re-zero my tool after any crash and keep running, figured a quick touch off was enough. Then last Tuesday on a 3 inch aluminum part for a local shop in Akron, I had a .500 end mill snap and I reset the offset but didn't check the holder. The next part came out .015 oversize and I scrapped a $40 blank before I realized the collet had shifted in the crash. Now I pull the tool completely, inspect the taper and the holder, and do a full indicator check on the spindle before anything else. It adds maybe 15 minutes but it beats redoing a whole setup or fighting a chatter issue that shows up two hours later. Has anyone else gotten burned by a hidden crash issue like a pulled tool or a tweaked holder that didn't look wrong at first glance?
