I have a PacMan like icon that never disappears. On my browser I cleared the cached data and try to reload the page. Even if I wait a while, the PacMan remains and I can't update my collection. I disabled my extensions but it does not change anything.
I don't know if this is because still card images are loading. In the past, we could alter the collection even if the whole set of image was not yet loaded which was great.
I do not use InnKeeper, I use firefox 106.0.5 (64 bits) for windows 11. The problem exists since the website has been changed for the Lich King extension.
The Lich King is available since several weeks, but unfortunately, the Lich King tab is missing in the collection. Note also that the tab icon do not match the corresponding cards (the missing icon is the warrior one).
