Blizzard's WC3 Patch completely screwed up the old 6.52d version. Runes disappeared when a player came close, some heroes skills didn't seem to work and a bunch of players already downgraded their WC3 game to keep on playing 6.52d with Warcraft3 version 1.21.

Tonight, IceFrog finally released the new map version 6.52e, which hopefully fixed the majority of those bugs. Let's hope the version is stable enough to be played at the ESWC Masters tournament.
