That entry is corrected in the new modding manual that will appear in the next patch. Currently the vanilla game unit numbers go up to 2082, so a suggested range for modded numbers is 2300 - 2999 or 2250 - 2999, since it is a given that at least some new units will appear in the next patch. The previous one added 100. The issue of the ever shrinking range of numbers available for modding has been brought to the attention of Illwinter.
