A CTD while operating on airgroups,
it happens when I click on an airgroup name on the left after doing some things,
e.g. before I had disbanded an airgoup, the 161a ITA FB Grp
then i went to pilots list, I filtered for ita and F (fighters) and reserve to see the list of pilots released
then I went back to air groups list
when I click on the 160a ITA FB Grp the game crashes
