CONFIRMED Trying to use Frostweave Net causes an access violation and the game to crash to desktop every time.
The WoW database is just totally corrupted on Blizzard’s end. I was looking at my mount list and some mounts aren’t even showing up correctly. For instance, “Vicious War Spider” shows up as Crusty Crawler.
Looking at Bugreporters link post above shows that there are several other items that are causing the same crash for people. Thanks Bugreporter for collecting these posts to help bring attention and hopefully get this issue resolved more quickly.
