As I recall, we only put 50 years of paleoproductivity data with that demo
version, just to save space; we actually run it up here on 400 years (the
simulated productivity from AD 901-1300). So what you see here, for
example, at year 51:

is that agents are suddenly sampling some random kcal of maize that is crud
left over in the memory, and pretty soon they run out of storage and they
all die. When the agent being tracked by debug dies its agentTime will also
become some crud left over in the memory instead of a measure you can use.
In that REMOVE line, the first n is the number of agents currently alive;
the second n is the number of agents that have even lived.
In other words, so far as I can tell, within the limits of what it's
supposed to be doing and the paleoproductivity data available, the sim is
working OK. We are currently on version 6.x up here so that it is a little
behind what we are working on now but is still useful as a demo I hope.
