Hi TDW, hi misha...
Misha - congrats

@TDW, same situation at my side. No markers. I didn`r touch the .py file. So, sometimes, I can see the marker, but in general - not - as wrote Kaleun misha.
A bit confused because after tutorial mission (I sunk 3 units) on my map still sitting 7 markers
Best ragards,
