Its not that. At start, when I had the option to install it, I didnt. I had few radar contacts, for 3 patrols. Maybe it was my third patrol, or start of fourth, that my brain got stupid to drag that doodoo to my sub. I guess I got what I deserved

Best near ports to run only as much TC that doesn't cause mass lag.

If you're leaving port, you have an option to start outside the harbor away from all the traffic....use that option instead. It places you outside the ports contact zone.

I donot start at tender. I only start at 1000+ deep water. And yes, its a question about cancelling an upgrade, from 1 to 0.
