- Revert skill cooldown list not support found problem map server crash.
I will try check again.
* Fixed #101 - Warg Dash not beginning run action when used.
Timer interval, Waterball, Crimson Fire Formation and boss walk delay updates
- Reduced the timer interval from 50ms to 20ms (official value)
  * For a long time it is well known that the Aegis interval is 20ms, but devs have been hesitant to set it to that out of performance reasons; these days however, machines are better and there aren't really many 2000+ player servers anymore, so a 20ms interval is actually quite viable now.
  * Setting the interval to 20ms makes the server perfectly in sync with the client that expects the server to have a delay of no longer than 20ms.
  * All skills that are "chain-able" on official servers will now also be 100% chain-able here (previously it just worked to 40%), assuming there is no lag
  * Skills with cast time will no longer go off 30ms later than officially
  * Several others improvements in regards of client-server sync (timers are used almost everywhere)
  * This might increase the CPU usage by up to ~50%, if you have trouble running your server with this, you can increase it again in timer.c (TIMER_MIN_INTERVAL)
- Strongly improved the Waterball implementation (bugreport:9382)
  * The interval between Waterballs is now 150ms (previously 125ms); due to the timer interval it will alternate between 140ms and 160ms (yes, this is official)
  * While the Waterball effect is active, players and non-boss monsters can no longer walk
  * Added a server-sided canact delay each time a Waterball is shot, which is equal to the one the client gives; this is to prevent hackers from being able to mass-cast Waterball; you can still multi-cast Waterball if your aMotion is shorter than the Waterball interval (i.e. 186 ASPD or higher)
  * The Waterball effect is no longer canceled when the target hides behind an obstacle, but no waterballs will fly and no damage will be applied; walkdelay will remain, but there won't be any canact delay for the caster (meaning he can cast another spell); if the target comes out of its cover during the duration, it will be hit again (this also fixes an exploit against MVPs)
  * Waterball now has a max duration of 10 seconds, even if more water cells are available, the effect will stop; this means that level 10 monster water ball will now only hit up to 67 times
- Fixed Crimson Fire Formation having a knock-back effect although it shouldn't (bugreport:6949)
  * It will hit once every 20ms with no knock-back, regardless of whether the target is undead, non-undead or a player
  * If you want to it to display more "fluently" you would need to set the SKILLUNITTIMER_INTERVAL in skill.c to 20ms, but the performance loss is pretty big for something only this skill and Firewall would benefit from
- Bosses are now able to ignore skill-induced walk delay (#100)
  * They can for example walk after casting Sonic Blow and Waterball (see above)
- Minor description improvements
- Fixed item bonus for vesper card in pre re
- Fixed warning for infinite warp where count_rewarp increased when the player was warped near a warp

Land Protector, Ground Skill Splash, Storm Gust Knock-back
- Land Protector now behaves like on official servers (bugreport:5237)
  * Land Protector now protects from units being placed on it, no matter if they have splash range or not
  * Land Protector no longer protects from damage from units not outside Land Protector that splash inside
  * Meteor Storm no longer shows meteors falling if they would land on Land Protector
  * Pneuma can no longer be placed next to Land Protector
  * Also cleaned up the code a bit, so the checks are done where they should be done
- Ground skill splash ranges updated to their official values (bugreport:5237)
  * Lord of Vermilion places units in a 11x11 area with 3x3 splash range each
  * Storm Gust places units in a 9x9 area with 3x3 splash range each
  * Heaven's Drive places units in a 5x5 area with no splash range
  * Venom Dust now has a splash range of 3x3 and is consequently larger than before
- Storm Gust's knock-back behavior updated to official (bugreport:5237)
  * Each of Storm Gust's units will knock back "Away from center"
  * As units in the south-west are processed first, the knock-back direction will usually be north-east
  * At the edges the knock-back direction will be "to the outside"
  * Land Protector and Ganbantein will influence the knock-back behavior strongly, e.g. if Storm Gust has a hole in the middle, it will have a "suck in" effect
  * Added a config option for those who want the old "random direction" behavior from eAthena
