Some shipparts and turrets, like smoke funnel、searchlight and 20mm AA Gun, are unable to destroy by my shells. I tried the 3-50，4-50 and 5-25 deck gun, using AP and HE shells, but none of them could damage those shipparts, which in stock game could be easily destroyed.
Clean installed SH4，FOTRS v0.80 RC2，LAA，delete all saved files before installing.
