Enter a 64-bit O/S Ubisoft glitch where the Warlock hero has 5 tails which blur together on the screen. Deeply upsetting, since the only answer is to step back to the old 32-Bit Vista or even XP. Now, Heroes 5 can be played on an even slower O/S. Congrats, Ubi, with the "Five-tailed Warlock". Thanks to Astral.
