I have an issue where my contour lines are hitting one feature line for top edge of a swale, but at the next feature line (which is intended to walk the design surface back to existing grade) the contours are shooting off into nowhere, with no logical reason. I even checked the EL at the terminus of the errant contours, and it's a value not equal to the value of the contour line (spotgrade on 65.00m contour returns value of 64.9.
