Forum fatal error

[lorienn]

sometimes i randomly start getting a fatal error on a certain character and game just crashes when i log into that char but fixes itself after a while but other characters are just fine.
idk if i can post a screen shot here but the error says:
ERROR #134 (0x85100086) fatal condition
program D:/ wotlk/wow.exe

failed to read file
textures/minimap/e529b7df83871e6ddfd3fe047e1608.blp.
