Already fixed in the 1.3 patch? Well it isn't much good if they take their dam sweet time releasing the patch. Also didn't they make claims of fixing that issue in previous patches?
Maybe you should read and understand that since most people don't have this patch they can't enjoy the so called fix. In fact I won't believe custom map downloading is fixed until I see it. Epic doesn't have a good track record. Most people will not install beta patches, so just because a few people have it doesn't mean it works for everyone.
It's fixed. At least you cannot say they rushed it...
