Thank you very much!
Can you talk more about this "attempt to fix position lag"?
So, now players can break animations by walking and chain skills more fluidly (as it is on official servers and always was). This is what should happen, instead of punishing high APM players when they are trying to chain skills properly. This feature is really influential in competitive PvP scenarios, and that "fix attempt" was highly detrimental for high-skilled players.
But, indeed, you're right that there is clearly a bigger issue here - since editing that line DID FIX the problem, but introduced types of "forced bug position" that never existed on official servers (e.g., casting Arrow Shower with no arrows equipped while walking).
The interesting thing for me is that while kRO, at some point, did fix this position desync (so it's no longer possible to "force bug position" in the majority of cases on official servers), they did it possibly in another way, without messing up the possibility to break skill animations by walking (which is still possible today).
And again, thank you for your help!
