Your issue is in the function AddStatBonus at this line:

stats.Find (x => x.StatName == statBonus.StatName).AddStatBonus (new StatsBonus (statBonus.BaseValue));

You have several scenarios:

  1. Your stats list is null
  2. The statBonus variable is null
  3. The returned value from Find is also null

My suggestion:
Split this up into more than one line and add some checks to make sure you are not operating on null values.
