Hey everyone, we do have plans to label schematics to make it clear whether or not it is already known by your character, but don't have a timeline as to when this change will take place. It's definitely something we want to add to make schematics easier to assess!
You might want to fix the current behavior of schematics.
Prior to the patch, if you knew one, and tried to learn it, you just got an error message, but didn't lose the schematic. Now, if you try, you lose the schematic.
Don't you folks have a test server for this sort of thing? Or at least some sort of test process?
