i love NAM v31! i did find a bug, however... i can't seem to lay down any new 6- or 8-lane ground freeways with concrete medians... ones that were laid down with v30 remain, but if i try to extend them or click them with the RHW tool, they become medianless...
to the left, is an RHW-6C to 6S transition (with median) from NAM v30... to the right, is an RHW-6C to 6S transition (with median) from NAM v31... note how the media disappears between the two versions.
what do i need to do to restore my medians to their previous glory?
as well, do we install NAM v31 directly over v30, or do we remove v30 before installing v31?
