They changed this in the last patch without telling anyone. You have to take the untied bandana to your hands and left-click. The prompt for the action is not shown, you just have to guess to figure it out.

I can't get the bandanas to work in 1.03.151457 either. It works in 1.02.

Holding a bandana in your hands and pressing left-click (or holding left-click) does nothing - you are still holding a untied bandana in your hands.

Right, bandanas can't not be weared.

@Geez hi :)

Please check this ticket.

I actually have found two kinds of bandanas. One takes up two slots and one takes up three slots. The one which takes up two slots can be worn, the one which takes up three slots can not.

@Egobyte83 the bandana that CAN be worn will have likely come from a player who had it before they stopped working. For example, I had a character on public servers, 1 week ago, who still had a bandana on his head. This is because that character had the bandana for months,

Nah, that's almost 100% not it because (1) it's still too specific that the one bandana that can be wearable takes up two slots in the inventory and the other one takes up three, it's most likely a completely separate item family, and (2) the bandana that is working for me (a two slot bandana) I found on my private server, a server which was created way after the whole bandana issue started.

@Geez hi :)

Please:

1. Change classname in loot table(types.xml) from "Bandana_{colour}" to "BandanaHybrid_{colour}"
2. Remove deprecated items

3. Add some new

-BandanaHybrid_Blue
-BandanaHybrid_Pink
-BandanaHybrid_Yellow

I am not finding a "Bandana_{colour}" entry in types.xml. I only have the entries displayed on your image.

Hello PR9INICHEK.
The original report of this ticked described the issue of inability to tie bandana into either facemask / headwrap and being worn. The cause of that issue was the same as in T139403 and it is addressed with the change to the bandanas that should be present on the current stable version - bandanas change into the wearable version through drag and drop to the corresponding slot on the character, rather than through usage of an action to tie it into specific item.

Geez

@Geez
