I took off with 2x 1700L Wing Tanks + 2x MAGIC + 2x GBU12.
I dropped the GBUs on target and went Back to base.
I used the Vide Vite to dump fuel before landing (open cache + press button), keeping the tanks under the wings, no drop in the beautiful sea.
After landing I went to refuel + rearm with the same configuration but the Wing Tanks remained empty.
Thinking I did it bad I tried to rearm a second time, but wing tanks still empty.
I rearmed with configuration without wing tanks: 2x MAGIC + 2x GBU12, and after that rearmed with initial configuration, here I got full petrol.
Thanks RAZBAM for your efforts.
