AGS: Quest for Glory II: Trial by Fire Remake - Winning Keapon Laffin's Game causes crash

[bliznik]

Winning the Wizard-only game against Keapon Laffin causes the game to crash. Upon winning, right after the "cloud/thunder" animation, the game will crash out. I've been able to replicate this three times.

System is Windows. ScummVM version is 2.6.0git3339-g5cb8202d9bc. Game is the AGD Interactive version of Quest for Glory II.

The crash log doesn't provide any data. There are 3 error messages about the sound not working properly (e.g., "Audio stream did not support seeking!"), but those error messages occur far before I even talk to Keapon Laffin, so I don't think those error messages relate to what causes the crash.
