Ah, I think I understand what was happening, and I think I can repro it now. It seems like a location section can not have a "chr/act" pair before the txt/img declarations. That is something I want to fix for a later version, thanks for finding that!
I am glad you like the engine so far. And hey, no donations needed (but thank you for offering), I do not in fact accept any :) The best way to show your support for Yarnspin is to use it and enjoy it, that is all I want it to be :)
