Trying to do the heart quest just now (10.30pm UK time) and all is fine until I ask Cessillia to mix up the potion at which point I become stuck to the spot. Unable to move forwards, backwards, sideways (no walking annimation either).
Dodging does not resolve the issue (runs the annimation but on the spot), also tried sitting and sleeping with no luck – welded next to her unable to pour the potion over anything.
Someone else set off some spiders (so it seems it doesnt affect everyone!), and I can fight as long as its stood in the spot im stood on – daggers thrown as well as slashed. All landing hits.
The being stuck issue is also not reolved to tp to Wisperwell waypoint – just end up stuck there instead.
Loggin out and in did solve it until I spoke to Cressillia again at which point suprglued to the floor again
EDIT: Checked ip it was on 206:127:146:56:0. Relogged and ended up on 93 which still had a bloke there from earlier (before relogging to 53)
Multiple players getting stuck at it. (4 at least on 93 while I was there)
