The two variables export and centyear2 are not in your model. You
wrote that this is your problematic model:
xtmixed quantity year centforestarea2 centgdp2 centlandarea2
centpopulation2 || _all: R.country || _all: R.genus

Please provide the summarize output of all the variables in your model:
. su quantity year centforestarea2 centgdp2 centlandarea2
centpopulation2 country genus
