Heya,
I found no problem with them after say getting rebased to wilhelmshaven .............................
I have actually started a fresh career with them installed
Finally got the pc back to health after severe overclocking instability (my fault lol)

so i can rule out oc'ing as a ctd cause now, but i have just had a ctd after sinking most of the sitting ducks in danzig bay
I have just checked whocrashed, and it looks like the ctd was caused by a mod (never had Dbgview enabled did i grrrrrrrrr)
But i think it's the flags for a guess, also, pinner2010 uses his before FX update, and he didn't get a crash while doing baltic missions (well i don't think he did)
So conclusion is for me, after initial mission/s they're good to go when installed after FXU and Equip upgrades, or before both of these
But interestingly, the dates and certain items both equip upgrades and sub flags sgre are not the same, only on 2 sub variants though, so i'll look into sorting those items and see how it goes
I think i have cured my ati driver error too (watch, i bet i've spoke too soon hehe) so deffo pointing to the conclusions above, just gotta rule them out one by one
