I had the same problem and I think I figured out how to fix it. You have to go into the scenario editor and set a trigger where the effect is “Use Advanced Buttons.” Then test the scenario and you should be able to use them. Then just quit the scenario and it should work. If it happens again, just repeat the process.
Its happens again,so i confirm bug happens when you are in EDITORS,and click menu ,as soon as click options,every setting will disappear (language will be portuguese-brasil,resolution will be 633*356,and advanced commands gone…)
