Comparing the MasterBook Simple Movement rules with the Complex Movement rules shows a small glitch: a character with a MRG of 4 has a Simple Movement range of 8m, and a Complex Movement range of 6m. This is obviously wrong, so a fast fix could be to add the Simple Movement range of 8m to the Complex Movement range of 6m for a total of 14m. A character with a MRG of 4 would be able to run 14m a combat round with this rule modification.
