A Merge always counts as one Plot

no a 4er merge are 4 plots if my max plots 4 i can only have 1 4er merge and with reset only the origin is remove from max plots so 3 are in max plots

Should a merge count as one or multiple plots? @jasonwynn10

merged plots count as individual plots for the permission calculation system
