Yes, stock SH3 wasn’t bad at all of what i remember back in the years.
Win 10 does really weird things sometimes... IE i set all my torp load before patrol and i end up with other load!

Happens at least twice to me.
Other thing lately, in my last career patrol my tonnage was 27000 and in bunker log book nothing appears...tonnage zero! No medals, no experience, nada!
Win 10 is the best crap builded over last years.
