Those messages do mean that there is a bug somewhere; someone likely changed the C++ definition of a slot function and forgot to update the signal that triggers it.
I will file the bug reports. Before I do that would you provide some coaching hints as to what to look for? As I'm continually trying to learn more about this game, perhaps I can get lucky and patch them without filing the reports.
I understand the concept of signals and slots, but that is about all. What am I looking for?
