There is a bug somewhere causing parents to sometimes lose track of some of their children. I have not been able to determine how or where this happens. To address it for the time being, I’ve written a pair of routines that will hopefully reconnect children with parents when one has forgotten the other.
When drawing shown but normally hidden traits in the Unified View or Classic View trait lists, the text is now drawn with some transparency, which has the effect of ‘graying them out’ regardless of the actual color they’re drawn in. The options related to adjusting the transparency level are in the Display box in Program Options.
