Guild Wars 2

I have a weird bug where weapons shrink when they are stowed on my back. Greatswords look like swords, Longbows look like Shortbows etc. If someone could teach me how to link photos I will take some screens to show you.

You mean in the preview window, or in the actual game? I noticed this only in previews so far.

As for images, take a screenshot, upload it somewhere and go to “more formating options” via the link below the comment window. You’ll find the options to share an image url there.
Or attach it to your post via the “attachments” option.
