Errata

Mistakes happen, and sometimes players come up with situations the BattleTech designers, writers and testers never imagined. If you believe you’ve found a problem, report it in the appropriate thread on our forum. If you want to see what errata we have issued, here is all official errata issued for our products.
Catalyst rolls in any approved errata every time a product is reprinted.
