-------------------------------------------------------
== 08/16/2014 ==
KLS: (addmoreice) Trying out some unstable DB changes. Do backup your database before trying them as master will be considered unstable for a few days at least.
Uleat (Noudness): Fixed a floating-point comparison error that led to the notorious 'client bounce' (this is not related to the
'mob falling' due to not having maps installed.) This fix also eliminates a sizeable amount of unnecessary out-going packets due
to invalid orientation corrections.
Note: This patch is probably of significant enough importance that admins may wish to manually apply this to older server builds.
The number of packets reduced per second should be approximately (num_stationary_close_clients * (num_close_clients - 1)). This will
likely have the most effect in zones like: Nexus, Bazaar, Guilds (Halls) and RAID INSTANCES - where players don't move around a lot.
== 08/15/2014 ==
Uleat: Reactivated the Bot::Spawn() code for sending post-spawn wear change updates..temporary until I can sort out the proper usage.
