The mistweaver’s statue stays where you last (up to five) placed them. they’re all showing up on the ui icon near the top left… Unfortunately, none of the totems will work either.
I encountered it while running a dungeon, tried it again in world-- still happening, relogged-- still happening.
I was just about to post on this.
I also noticed this in dungeons.
I track the auto heal and noticed my totem wasn’t doing it.
So this is some mixture of a visual bug but also have see it very frequently not applying the 8 seconds channel to the target
EDIT:
The visual for the channel also appears to only come from the first totem that was placed
EDIT #2:
I can confirm that the auto channel will only originate from the first totem cast, until you cast 5 more.
This is a pretty breaking bug, renders the talent useless.
if only… they all worked at once…
I can comfirm this bug, its happening to me outside of dungeons as well, even after I changed talents. It’s quite game breaking ( in a bad way , they dont channel).
Same thing, thought it was a connection thing but other players can see it messing up as well. At the very least the only fix is whenever you die it resets and the 5th allows it to possibly heal again at new place. Doesn’t always do so though.
yup i noticed it once i jumped into a mythic dungeon. really annoying 
i hope they can fix this soon otherwise its gunna suck doing castle nathria with the bug still active.
Patch notes don’t look promising.
Can we get a Blue to confirm this is being looked into?
If they dont fix it today, just manually cancel your statue by clicking the ui totem on the top left then resummoning or by using the macro [/click TotemFrameTotem1 RightButton] then resummoning
It was impossible to do pvp last night with the bug. couldn’t keep up with removing the statue manually. 
please blizzard fix it.
