Sometimes, when reviving from health provided by party members, my character makes the animation as though I were giving health to someone else, then does the typical heel-spin and falls on the ground again, throwing out the same amount of heat particles as before. The split-heart icon above my head reappears, and I press attack to revive myself once more and walk away, some heat particles left behind, though that appears to only be graphical.
In the past I've encountered this issue and shrugged it off as a simple error and moved on.

But recently, this happened.
Lag got worse and worse the more times I tried to bring myself back up. I have no idea how I managed to get out of this other than waiting for a space of time and trying again, which did the trick.
