I’ve recently replayed Warcraft III’s Reign of Chaos Campaign, and have encountered a bug where after completing a mission which precedes a cinematic (i.e. the mission where Arthas kills Malganis which precedes the cinematic where he murders his father) the ingame soundtrack keeps playing on top of the cinematic itself.
This keeps happening in other cinematics in the other campaigns as well. Such as the Night Elf campaign where you hold off Archimonde from reaching the world tree which cuts to the cinematic where he gets killed by wisps.
My specs in case it matters:
Ryzen 5 7600X
RX 6800XT (Driver version Adrenalin 22.11.2)
Trident Z 32GB 6400mhz kit
Windows 10 Professional
