@ -4,6 +4,11 @@ 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.
2006/07/12
* Fixed exploit in pc_bonus there are no checks that check that the value being
added onto a status don't make it go below zero, which means if you have a mineral
card and reset stats it reduces your base attack to lower than zero, making it
go up to 64000. Fixed by adding a check for SP_BASE_ATK, although i recommend
doing it for other status bonuses also [Zido]
* Recoded NJ_BAKUENRYU to behave as I understand it best from the
skill-description (since Haplo told me this skill doesn't really has video
information or anything...) [Skotlex]
