- Added a check to prevent casting ground skills on a target and vice-versa when said skill use packets are received. It really shouldn't be exploitable, but doing that certainly makes the server print a lot of "unknown skill used!" messages.

@ -4,6 +4,10 @@ AS OF SVN REV. 5091, WE ARE NOW USING TRUNK. ALL UNTESTED BUGFIXES/FEATURES GO
IF YOU HAVE A WORKING AND TESTED BUGFIX PUT IT INTO STABLE AS WELL AS TRUNK.
2006/11/07
* Added a check to prevent casting ground skills on a target and vice-versa
when said skill use packets are received. It really shouldn't be
exploitable, but doing that certainly makes the server print a lot of
"unknown skill used!" messages. [Skotlex]
* Fixed map_foreachiddb and map_foreachpc so they don't encapsulate the
variable arguments into a double va_arg list. Thanks to the Ultra Mage for
the tip. [Skotlex]
