So I was messing around earlier and I noticed something strange.
Normally when I change direction (on old eAthena emulator), I can immediately high jump in that direction (assuming instant cast).
But upon changing direction, there is a little delay I have to wait before I can jump in the new direction.
If I use the skill before this little delay, the server still thinks I'm facing my old direction.
It will jump in my old direction, despite me facing a new direction.
Example (try picture in your head):
My character is facing North.
I click Northwest and quickly use instant-cast high jump.
Character high jumps North (instead of Northwest), despite the fact character is facing NW.
Jump completes, character still facing NW, if High Jump is used again it will jump North, despite still facing NW.
Anybody else experienced this? I don't remember it being like this on old eathena. I'll try to upload a video later.
