Guild Wars 2

Today I got on GW2 to find that my selfless potion was gone.I had always kept it in a my shared inventory slot so that all my characters may use it.I am really disheartened by this as I got it originally got it from the attack on Lion’s Arch and I worked for days to be able to get it.I just want to know if this is a bug at the moment of items disappearing from the shared inventory slot.Below are two pictures of me with the selfless potion as it is the only proof I have of me with it.The other picture is of my inventory and it not being there.Hopefully someone has the answer to this.

So today a friend and I were duoing Arah P2 because of the challenge. We were having a smooth run until we died 75% through the fight with Alphard Serpent of the Seas. We waypointed back and walked are way over to were Alphard is. However we were greeted with the bone wall that is put up during the fight still intact and impassable. This is not a one time thing; I have seen this on other runs probably about 4 or 5 times in my time playing the game. below are pictures of the wall still up and that nobody is on the other side with Alphard.

Recently I started making the components to craft the Flameseeker Prophecies and I was going to make the gift of history. I needed my tailoring level to 400 to make the gift obviously. But while I was crafting I stumbled upon a bug that seem to stop me from crafting. I was trying to craft Cured Thin Leather Squares but it wouldn’t let me. I would click craft it would begin crafting and it would not give me the leather squares. Luckily it did not take the leather from my inventory but it would not craft the leather that I needed. This has also not been working for any other material or item that I try to make in tailoring. Other crafts work and I have tried to deactivate tailoring and reactivate it but nothing. Hopefully I can solve the problem soon. Thank you for your time.
