Way way back when Forgotten Heroes was first published there was an error on the veteran skill counter being mislabelled as "Thumper". This was an error that was in place long before any of the current LnLP team were around and able to fix it. In fact, it went through 4 or 5 printings including ours without it be corrected.
So, some of the long time fans of the LnLT series asked us to please correct it and provide a PDF replacement, well we FINALLY did.
Thank God we work on games and not nuclear weapons.
