I uploaded a map service onto ArcGIS Online and noticed that I'm having a problem with one of my layers. The layer is a Shapefile and consists of polygon features. There are 13,766 features but only 13,566 are showing up on the map I created. As I mined into it a little more I found one block of 100 where every feature from ID 7800-7900 wasn't showing. I tried copying and pasting those features on their existing location and they don't show up. If I create a new feature it shows up but I'm still missing 200 features. Any thoughts?
