Not sure where to put this since I'm not sure it's a bug or my fault or maybe even an issue with the excellent life saver Tophat.
Anyway, as per another thread I wanted to add åäöÅÄÖ to the standard font and got the recomemndation to use Tophat to expand the available characters. It work straight away with Asheville Bold, but when I tried to do the same thing with Light my game would crash instantly.
I switched to my Mac to see if that helped and I got an error message saying there was a mismatch between the number of characters in the png table and the fnt file.
My "solution" was to delete a bunch of characters I wouldn't be using (the japanese ones) and then it worked.
