Since spirit is too lazy to read I will repeat some other users here:
at the moment the main problem of gamestudio is the map compiler. it doesn't work properly for polygon soups. (Ventilator)
That was my original question that started all the screenshot posting: Are you indeed using WED and found a bug, or are you just repeating what other people say?
When you are a WED user yourself and found a bug then I say it the third time, report it to Conitec.
But just spreading rumors about bugs is not honest.
