Bob,

I found a bug with map switching on restarts. This bug is similar to one we had 
before where it is messing up when the current year does not match the first 
year of the simulation. So you need to look at how map switching is being 
treated in years beyond the first. I can't pin it down further than that since 
I am not familiar with the log files (map, maps, mapManager.txt).

Here is my setup:
2 year simulation
10 day dispersal (this could be shorter)
3 food maps:
First food map is for the first day only, 0 chance of catching any prey
Second food map is for the second day only, 100% chance of catching prey that 
is not energetically favorable (i.e. disperser still loses energy)
Third food map comes in 48 hours after the start of the simulation and lasts 
the rest of the season, 100% chance of catching prey that is energetically 
favorable (i.e. disperser gains energy)
So look at the 2013Female000000.txt. On the first day of dispersal you can see 
the 0 for ProbFoodCap. Starting at 3/16/2013, 6:00 PM, you can see the 
ProbFoodCap go up to 1, but it still loses energy slowly. At 3/17/2013, 6:00 
PM, you can see the animal start to gain energy as the third map kicks in. That 
map lasts the rest of the season. Note that I restarted at several points and 
everything worked fine.

Now look at the 2014Female000046.txt. This is the same run as before but now in 
the second year. It starts off as normal, 0 for ProbFoodCap. I restarted the 
run at 3/15/2014, 9:00 PM. You can see the ProbFoodCap jump up to 1 (summing 
the partial timesteps), but only for two timesteps -- at 3/15, 11:00 PM it goes 
back down to 0. So it loaded the wrong map for two timesteps. 

I also restarted the run at 3/16/2014, 9:00 PM. That should be the second food 
map where they are still losing energy. But you can see the jump in energy from 
9 to 10 PM, so it loaded the third map instead of the second. But once again 
only for a couple timesteps.

Then look at 3/17/2014, 8:00 PM. Here the ProbFoodCap goes down to 0 for the 
duration of the run. When it should be the third food map where it has a prob 
of 1 and is gaining energy.
