This is why nobody should be in control of an NPC base, not to mention multiple ones. Now we have these two children screaming at each other about which toy belongs to whom. It also explains why faction progression is stagnant (as you say): It's because none of you is willing to give up an asset because it would be a "victory" for the other. Roleplay is all about giving and taking, you two only want to take and obviously that leads to stagnation and dispute.
