Unfortunately I cannot tell how it disappeared because I just noticed it now when adjusting the altitude for the engine exhaust, but as the title said, the design info menu is gone for me and would not show for how many imes i click the tab.
This definitely is on my side, on my pc and may be just operator error (i.e me being stoopid) why it wont show so im happy to delete this report if it is the case.
