Fight against Seether - music bug


Rear Admiral
So, after speaking to the GOG team, it became obvious that the DOS version of WC4 that you can download on Good Old Games does not work. Therefore, I bought another copy on eBay, and this one works great with a few DosBox tweaks.

However, I did run into a strange bug that doesn't seem to occur in the DVD version : In the last mission, right after the cutscene that shows Seether doing his mine trick, the music sometimes stops playing (it starts playing again if I kill Seether). I can always use Alt-O to turn the music back on, but it does kind of ruin the mood. I was wondering whether any of you had experienced this problem before?
