I am building all of my production factories into the map. I've got 45 so far. No matter what order I put them in, the 45th factory does not show up in the Global GUI list. I've tried rearranging the order, and no matter what, the last one will not show. The log is clean. Player triggers at the actual factories work fine bringing up the GUI.
Is there a limit on the number of factories allowed in the Global GUI?
