(Bots/FakePlayers) - getting errors in gameserver console

Miami · April 8, 2022

There are a lot of errors appeared when I enabled and configured bots for my server.

Bots are created and looks functioning, but that flood in error log is annoying.

Here are the examples of errors

java.lang.NullPointerException: Cannot invoke "l2jorion.game.model.L2Skill.getEffects(l2jorion.game.model.L2Character, l2jorion.game.model.L2Character)" because the return value of "l2jorion.game.datatables.SkillTable.getInfo(int, int)" is null
