[UAH] How much land Baganda have lost in Luwero Triangle?

The Luwero Triangle (Mpigi, Mukono, Mubende and Luwero) where much of the guerrilla war was fought in the first half of the 1980s has a total acreage of 22,000 square kilometers. According to the 1980 population census, Luwero Triangle had a total population of 1.5 million.
During the war some one million people in the Luwero Triangle were pushed into the forest for protection. It has been estimated that some 700,000 people lost their lives during the five year war. It has also been recorded that some Baganda who fled to Kampala, Masindi, Jinja and Masaka towns etc did not return to the Luwero Triangle when the war ended in early 1986. This means that about half of the population returned to the area.
If we assume that the half of the population that returned reclaimed their land, properties and cash in the banks, then the other half of the land, properties and cash in the banks were unclaimed.
But we know there is no unclaimed land, properties and cash in the banks. So, what happened? Who is occupying that land, took over those properties and withdrew the cash from the banks at home and possibly abroad?
Can someone help us understand what happened?
