If you're in a gang (natch), and attempt to Train Stats, Gangpaths "bleed through" the point assignment screen.
This makes it difficult to assign points, as it resets the lightbar and breaks the continuity of the ascii (gangpaths will overwrite the current line of ansi as well as the line below your current line). This also, of course, means that Mega will fire any triggers you may have set for GPs.
This bug is really annoying. The entire gang has to announce theyre training then everyone stays silent till theyre done.
