So you are the same one reported this issue at git. I think ive replied there. Btw below is mine when I tried to start the server. See the comparison with yours.
Try to check is it true the sql is execute and exist in you database, since I saw a 'null' there.
Then how you solve it ? Just incase other people have the same issue as yours too.
Then that means the item isnt exist in itemdb or cant be read by itemdb
To be honest a lot of question already being asked for quite a lot of times. You can use some googling skills here.
I have some in my playlist but not in english.
So after that you can be more specific about modification that you need.
From your statement 'the guild is at the maximum level', that doesnt mean that the guild already up skill guild approval.
Or else list all of your modification or setting for KoE then, the information might helps.
Did you already up guild approval skills ?
Or do you have some custom modification about attack range ? Since someone post their issue can't attack Emperium and figure out he modified attack range.
