A PLM simulator's convert to M-BOM appends rows every time, so running it twice doubles the BOM. Converting a conveyor assembly a second time with no E-BOM change takes it from 10 lines to 20, with every line ID duplicated, and the duplicates flow into the purchase BOM, the planning BOM, the cost rollup and the exported BOM. The fix spec keeps unchanged lines, adds only new ones, and supersedes dropped lines with an effective-to date instead of deleting them.

Analyst note
From the Grok pain-radar digests, Nov 10-11 2026 (Nov 10 8:41 AM ET through Nov 11 7:41 AM ET digests plus the Haitch editions). Verified live 2026-11-11: issue/PR read; title and state confirmed.
What it costs a team
Modeled annual cost
$30,000
For a team of 5
Prototype delay
3 days
Modeled schedule slip per occurrence
Time lost
240 min
Per engineer per month, about 1 incidents
How the cost is modeled
240 min/month × 5 engineers × 12 months = 240 hours × $125/hour = $30,000
