OK, I have finally collected 100% of the fireflies but my happiness was short lived. This is the reason:
This was BEFORE I installed Twallan's traveler mod.
When I analyzed the unique number of rocks before the mod was installed, I traveled and unsurprisingly, the percentage of rocks analyzed dropped. So I installed the traveler's mod and the issue was fixed...so it seems. When I have analyzed 121% of unique rocks, the sentence pertaining to "Awesome Rock Collector in the Universe" was not BOLD in colour! It had seemed that I have not collected 100% of the rocks but 121% of the rocks!
I am deeply frustrated as I am trying to create the perfect Sim where all his attributes are being maximized!
Is anyone else facing the same issue?
Must I start ALL over again in creating that elusive perfect Sim where all his attributes are being maximized? And yes, I am a hardcore Sims 3 player. I am very, very disappointed. I should have installed the mod BEFORE traveling!
