Crash on the Okuma ate my whole shift setup

Running a 5-axis job near Toledo on Thursday, I forgot to re-zero the Z after a tool change on the AL4. The spindle plowed straight into the fixture and snapped a 3/4" end mill, plus gouged the vise pretty bad. Operator error on my part, no doubt, but the odd part is the machine didn't alarm out until the spindle load hit 140%. Took me 4 hours to remeasure the tool offsets and rebuild the fixture. Has anyone else had a crash where the control let it run way too long before stopping? I feel like the load monitoring on this model is set too loose from the factory.
