Taekwon Stance & item/skill use bug (cannot use skill in combo time)

Hi,

This is a bug that's been happening for a while now that occurs for both TaeKwon and TaeKwon rankers, and it occurs for both Hercules and rAthena (both with pre-renewal settings).

When you're attacking a monster and a kick stance (Axe, Counter, Round or Whirlwind Kick stance) gets activated, and you try to use a Fly Wing or Butterfly Wing right after, it won't work for a whole 1.5 second. Not only that, but the item gets used up as well.

It also occurs when Break Fall gets activated on its own (This also happens for Soul Linker and Star Gladiators).

If you're a TaeKwon Ranker, it will also occur after activating a kick (except Flying Kick), since I guess technically after a kick, another stance is activated, so it's waiting for your input to use another kick.

It's like during those stances, you're forced into a certain mode where you're limited in what you can do, and that can cause many problems.

Hopefully this made sense.

Thanks.

Edit:
Videos of different scenarios where it can happen (check how the fly wings gets used up when I try to use them in different scenarios):

Edit 2:
I just now realised there was a similar topic here, though no one answered/confirmed:

Edit 3:
It seems when the stance occurs (and you're prevented from using Fly/bwings), you're also prevented from using most of your TK skills, like High Jump, Warm Wind, Running, TK Mission skill, etc. (all except Flying Kick), at least until the "1.5 sec" cooldown goes away from the stance. It probably prevents most other skills too (Teleport from Creamy Card, Heal from Vitata Card, etc.). Back when it was working properly, I was able to use other skills while the stance was up, as well as my Fly Wings/Butterfly Wings properly.

After further testing, I realized Fly Wing/Butterfly Wing ultimately uses a skill (Teleport) for them to work, so I guess the main issue to fix is not being able to use skills (except Flying Kick) during TK's kick/breakfall stances when they're triggered.

Edit 4:
After even further testing, it seems the bug (where you can't use skills and Fly Wing/Bwing gets used up but does nothing) seems to actually occur during the timer of any skill that allows a certain time for another dependant skill to be activated (e.g. 1 of 4's TK kick stance --> TK kick, Breakfall --> Flying Side Kick (added damage, also requires no aiming, just hit the skill), Double Strafing --> Beast Strafing (but only occurs if you're soul linked), Triple Attack --> Chain Combo (and so on for Monk combos), etc.). It seems during that timer, something is preventing other skills from being used, while also making itemskill (skill from items) not work, but still consuming them. Hopefully this all made sense. It is perhaps related to SC_COMBOATTACK. Interestingly, you're also unable to move during the timer. Maybe in status_change_start in status.c...

(Try soul linking a Hunter class, then using Double Strafe on a beast/insect mob and then try using Fly Wings right after. It won't work for 2 seconds (the same time that you're allowed to use Beast Strafing) and will still consume them, and other skills (including another successive Double Strafe) won't work until that timer is done.)
