Two-Stage Ditch error

[Amy Towell]

Hi - It looks like errors like this have occurred before but on different tools. (I'm getting it on the Two-Stage Ditch tool currently). Everything else in this HUC-12 worked fine and I've completed several other HUC-12's recently and this tool did not do this. Any ideas?
