We have staff who edit our sewer manhole points daily. Every month or two, the feature extent on this layer gets way out of whack. We haven't been able to pinpoint any specific editing process that we think would cause this. I typically just recalculate the feature extent and move on, but we'd like to find a permanent solution to this issue. Has anyone else experienced something similar? Our point feature class is stored in a feature dataset using our local state plane coordinate system. The data is always edited in a map document using the same coordinate system.
