Title: I've fallen and I can't get up
Description: Occasionally a movement impairing debuff expires, but does not go away. This happened to me in Grafu Castle (bear knockdown), in Survival mini-game (Malatina's wand knockdown), in siege (stun that occurs when you are invisible and come close to eye). The symptom is that debuff timer counts down to 0.0 and then stays at 0.0 instead of expiring.
On enclosed screenshots, you can see the name of debuff, the duration, and the timer showing that 6 seconds went by but debuff remains.
Version: 6.0.5 and earlier.
