Every place I am sent to patrol is mined or I am to confirm if it is mined!

I haven't seen a trace of a convoy in more then 1 year (Game Time).

Current date is Sept. 13, 1943 - Current Mission: I am to maintain strick radio silence. My order send me to verify if La Parouse Strait is mined and patrol the Northern Sea of Japan area. When I finish patrolling the SOJ, I am to return via the mined strait and patrol down the east coast of Hanshu Island as far South as I can go before returning to port.

Every radio convoy report is always as far away as it can get(WTF).
I am running PE4, ROW Sound Effects, RSRDC, Environmetal_4.2 (Scene.dat only), Poul-Sound_for_SH4(Really good btw, from AotD).
Is it normal in RSRDC_550 + patch to not encounter convoys like this?
