when baylor knocks u down character starts doing that all time, stand up and falling again and again until doing restart.
is this will be ever fixed? a bit annoying. it happens on soh too, also with cr mobs too. it's funny to see mobs sliding but still. it's nonsense.
i fix that very easy and i guess it should work for you as well: just turn off your dualclass hp increase and turn it on again. or in case you dont have a dual class, just ask someone to pull/push you can be a tank, healer, mage (wind stance), archer, dagger :d
this bug is a known thing and kr partners do not fix it... it can be removed not only by relogin, also mount/dismount your horse helps
