I donated my complete 65712 sqm of land and my tier to my group today. Afterwards the land tab in the group information window showed that our group was allowed a total of 72652 sqm of land, which I thought of as some group bonus. Of course, allowed without changing the tier of $195 monthly, I thought - why else would it show those 72k sqm under "total contribution" and 6940 sqm as "land available"?
So I went and bought an additional 3072 sqm of land, and deeded it to the group right away. Now I see that my tier jumped up to a monthly $292. I don't understand exactly why? Why would it show this land as available and then raise my tier, when my total land, all deeded to the group, is now still below the 72652 sqm that were shown as allowed maximum of land before?
