It should say "Congratulations!! You have recived "item name" for your effort in killing this monster!" as a guild message after recieving #616, but as you can see from the screenshot that is not happening.
dispbottom("Congratulations!! You have received '"+getitemname(.@itemid)+"' for your effort in killing this monster!") is the part of the script that isn't working.
Hello,
I was using the client provided in this thread by you, but clearly it is missing the plain text description option, because I managed to fix your error by selecting that diff and diffing a new client myself.
Good day!
