Basically you can disband the imported units prior to buying them, placing them on the battlefield from the "destroyed" units tab for free and all this without command points restriction (air or ground). You can even remove them again from the scene and get the RP's back you never payed for them. This way you can "earn" all the RP you want and then place all your imported core forces in the scenario for free... it's not cheating if it's an official game mechanic, right?

I'll attach a screenshot of a freshly started Panzerkrieg campaign using this mechanic, observe the command points and RPs. I just couldn't place more units on the map because of supply restrictions.
And playing the Tallinn Beta Scenario I noticed the water colour glitches (mentioned by another user) of the coastline and bridge hexes still remains. As seen beneath Haapsalu, Kirbla or at Virtsu:
I know this aren't as important bugs as having the customers a clean install first, but I'm just wondering if they are going to be fixed in later patches?
I'm playing the v5.2.3 64bit version of the game on Win7
