Guild Wars 2

dumb question but I seem to only be able to compact the first bag. shoulda asked this question long long time ago but anyways. it only lets me compact first one

At a guess, it’s because you have specialty bags, not basic ones. Only the basic compact.

• Basic — No special properties.
• Craftsman’s Bags — Looted crafting material is placed here first. Their contents do not move when inventory is sorted.
• Oiled Packs — Looted junk is placed here first. Their contents do not move when inventory is sorted.
• Equipment Boxes — Looted weapons and armor are placed here first. Their contents do not move when inventory is sorted.
  Fractal Equipment Boxes further refine this by also filtering by a specific rarity: Masterwork, Rare, or Exotic.
• Invisible Bags/Invisible Packs/Safe Boxes — Items in these bags cannot be sold to merchants nor at the Black Lion Trading Company. Their contents do not move when inventory is sorted. Using ‘Deposit Collectibles’ will not affect items inside invisible bags; however, items can still be deposited individually using the right-click menu.

Bags which are functionally the same as basic ones, like Candy Corn bags, the Karka Shell Box and the Uncanny Jar will also compact.
