Democracy 3 Africa crashes when loading up nation

An error box appears which reads the following when I load up a country, the game music still plays and the game loading text continues to scroll until i press “Okay” and then it becomes non-responsive and crashes.

[SentientMachine]:…/…/src/SIM_Simulation.cpp 602

seems similar to this thread:

Hi TheNote, I get the same 602 error as well just now and then a crash just like you. Is this a bug or?
