I’m having the same issue. Out of curiousity, are you also playing on Normal?
Also, did you trigger any particular chapter end flags (bonus EXP, having opened all the chests)?
Edit- I found my debug file in saves, and it appears to be the same error with the “Aen Sidhe” audio file failing to find. If you check under your save folder, I would bet you are having the exact same issue
Edit II: Tried the fix Budd suggested higher in the thread. Audio file was named “Aen . Seidhe” and the level six track was changed so it is now Aen Seidhe as opposed to “Aen\u00a0Seidhe”, but it is continuing to kick up the error that it can’t find the music track. Any further suggestions?
Edit III: ok, MOTR, if your deebug has the same issue as me, here’s what I did to get the crash to stop happening
-1: go to the BladeandClaw.ltproj folder, go under resources find music. check to see the name of your tracks. if you have “Aen . Seidhe”, change that to “Aen Seidhe” - change it to a space
-2: also under the BladeandClaw.ltproj folder, find the gamedata folder, and you are looking for three files you can open in a text editor like wordpad: “Levels”, inside the folder levels, the file numbered “6”, and in the folder Events the file “6_Intro” in all three files, change any instances of “Aen\u00a0Seidhe” to “Aen Seidhe” (I recommend control+f)
-3: save the changes and you will get past the crash
