İ cant loot frostweave cloth.when the box is 'forstweave cloth' my box doesn't open. Please Help.... My name in Game Aidox

Can you post a screenshot of your issue?

This is issue with Northrend cloth scavenging, it sometimes show theese extra Frostweave cloth in loot window (it comes as separate position, not just increased total value) yet you can not loot it if you don't have this tailoring skill.
