Sudden stop of production Lea Co NM from multiple wells in T25S R35E SEC 1

I have a small acreage in this section but because of the section’s multiple wells I have enjoyed good revenue for many years. I just received the smallest check I ever received for a royalty payment. This drop from multiple thousands to pennies was without explanation from CoterraEnergyOperatingCO. who just took over from Franklin Mountain. Does anyone have info re what happened to cause production to go to zero?
