Bugreport » How to write a correct bugreport?

There are different categories, concerning bugs:

Items
Itemabilities
Troops (or call them creeps)
Heros
Other units (like summons f.i.)
Heroabilities
Unitabilities
Ressources (gold, lumber, bounty)
Display (scoreboard, text messages)
wc3 crashes
others

Your topic should contain at least one of these categories and a short description of the problem if possible.
Important for me to know is always the color or number (red = 1, blue = 2, ...) of the player that experienced the bug (in most cases that will be you, I think).
Other things I need to know are what you did last before the bug appeared, of course, the hero you played and every other unit that might be involved.
