artboard re-naming glitch
The newest version of Illustrator (and previous version) both have a glitch that occurs when trying to re-name artboards in a previously saved document that has multiple artboards. After changing the names of each artboard and then going to "export for screens", the name of the first artboard will revert to it's previous name before exporting. All other artboards will retain their new name. In order to correct this, I must save the file, and then re-name the first artboard a second time and save again. After doing this, all artboards will export correctly.
