A .str file is the information source for the process to coordinate the .bmp files. You could change the rotation direction there for example. It also seems the position part of priest_spell.bmp has been modified. But honestly I'm too lazy for it and str programs are mostly old stuff which often crash. Working with this s*** really freaking me out.
What you want is an edited priest_spell.bmp and freeze_ice_part.bmp.
