Thanks for the quick response , the fact is that if you open the server track file in the mission editor, you can see that a checkbox is selected in the server mission settings, and failures are disabled (the right checkbox shows this), I mean if you uncheck the left checkbox on this setting , the user himself will be able to choose the required failure, probability, time, etc. - this is very interesting for experiments, and does not provide bonuses in battle. It would be great to be able to choose for yourself. If something fails now, it’s most likely a DCS bug). Thank you for your work (server) .
