i spawn the L2RaidBoss and L2GrandBoss and after the restart deleted from the spawnlist help

Try adding it manually (when the server is OFF) inside the table from the DB (grandboss_spawnlist, raidboss_spawnlist, or whatever is called in your pack)

Surely l2j broken pack, there is a stupid config about saving the spawn.. So, check your configs and change it to true :happyforever:

ok thanks locked
