The crash usually happend when a strange taskforce appeared on navigation map. It consited only of destroyers, and if I tried to look on them in exernal view, the game CTD.
It stopped after I disabled the mod, removed the Campaigns folder, the one containing patrol objetives, campaign layers and so on.
Now I´m running the mod for over two years without a single crash.
And I must say I´m loving it
