Hidden mechanic/events insight

[Tarvi]

Hi

I played through the morning sun and winter war campaigns again after a few years and before continuing to the next campaign i hoped to have better insight in the few topics from my last campaign from the more experienced players to help me resolve my confusion on these issues if in fact my latest game version could be defect

1. I tried planning my specializations as expecting same income like in morning sun but after Suomussalmi i had recieved no points, is this normal?

2. I noticed in the content files of the scenario for viipuri an secret event as the bt-7 in ladogakarelia41 "Used goods" for captured t-34s that never triggered even though i focused the troops on the Baltic coast towards leningrad cutting off all supply and annihilating completely all enemy forces

3. In Tali Ihantala after attacking an enemy unit i recieved a new commander "Unto Petaja", i guess it is from passing a threshold for dealing damage in a campaign/scenario, i searched again in the content data and found out there are 2 more commanders for finland i had not seen, but couldnt find their requirements for unlocking

Thx for your response
