hmm check the gameserver files..and check the time that your server saves..everything on the wolrd..maybe its too many minutes...i think it must be like that:
# This is the interval (in minutes), that the gameserver will update a players information such as location.
# The higher you set this number, there will be less character information saving so you will have less accessessing of the database and your hard drive(s).
# The lower you set this number, there will be more frequent character information saving so you will have more access to the database and your hard drive(s).
# A value of 0 disables periodic saving.
# Independent of this setting the character is always saved after leaving the world.
# Default: 15
CharacterDataStoreInterval = 15
change it to 1? i dont know.. :/ i dont have strikers pack..but may it work!
