'Destroy Anti-Air battery' missions timing out?

On the Malden server it appears that the tasks for the ‘Destroy AA battery’ missions seem to auto cancel but leave the units in place and still active. resulting in significantly more aircraft being shot down because there is no marker to note the fact there is active AA.

Please use the bug report form for actual bugs, this forum is more for general feedback and opinions.

posted B/R. thnx for response.
