Launcher 1.7.41 — Play no longer crashes Wow.exe
Play used to wipe the whole Cache\WDB folder and then rewrite client files while Wow.exe was already starting. That caused WOWOW ERROR #132 (ACCESS_VIOLATION) a few times before the game stayed up. 1.7.41 only clears stale item/quest/NPC cache and does not touch Data or Interface while the game is running. Close the old launcher and download 1.7.41 — existing launchers self-update from the signed manifest.
