Mushroom aura is bugged so you can no longer see it, the aura hits you as it did previously but you can't see it to know you need to move and how far you have to move. Not raided since the patch due to illness, so I asume this is something that went in with the last patch. If it is intended it is an aweful change.
There's another thread for this issue that is marked as QA in progress so it is at least being looked into: https://forums.daybreakgames.com/eq/index.php?threads/nos-hashiss-raid-green-decal-error.290281
