Not you added the fog or dust smoke

[discwalker]

Because its new feature (Create weather conditions icon with clock) and initialization is incorrect in 2.5.3.21708 also.

If you open a mission with fog or dust smoke or you check one of the checkboxes and

create a brand new mission with any map these are remained checked.

(Why we test openbeta? Why we hunt for cause of bugs?)
