2. If trucks are all upgraded, then get destroyed - all the upgrades should not need to be purchased again. This is just silly, needs to be fixed ASAP.
If I place a unit in the field and it is destroyed I do not expect its replacement to have those upgrades.
It's a risk you have to take when leaving the base sector.
edit: While we're on the topic of 'necessary' changes for OKW can we please lose the 6th man with the Pzfuss G43 upgrade, delay stuka timing and increase assault artillery cost. Thx.
