Lost all war crests is patch

[Gladiolix]

Just lost all of my war crests on my shaman. Quit game yesterday with 3,6k warcrests on my bag, logged in today to find out empty bag space where I left them. Did many many relogs, checked both banks many times. Tried buying 10wc worth of potions to find out if it was visual bug, couldn' afford any. GG. Propably related that I had stacking issues with war crests just monday, being in 2 stacks and not being able join them (1,8k each stack).
