The ship contours (Major Renegade's V6 in my case) cause the minimap to go blank.
The Krab V3 crosshairs are working for me, as are Atmaxx's colored tracers, the extra zoom camera mod, and the Tracks_Destroyer OTM.
I turned off all of the 'various mods'; I'd seen a posting suggesting that the damage and in-battle clock mod was locking things; my original selection had the Fog Remover, Clear Vision, More visible torpedoes and splash hits, and the damage and in-battle clock, and with these selected, the client locked at the battle loading screen; after I deselected them, I got the blank minimap from the ship contours. None of the other mods I'd selected appear to have been problematic.
