there's some missing procedure in the database, some of us maybe already knew what is it but still keep it for them self
but dont asked me, i dunno it either. for me, i just disable the auction and moved on
I did an experiment a few months back using 2.2.3 server base files and a 2.2.3.2 Client.
What i got was working mail/Honor guilds and auction house. I think the 2.2.3.2 database every one has is just a copy of the 2.2.3 one without having all the correct procedures and table the 2.2.3.2 zone needs.
If you think 2.2.3 is pointless think again you can get gold points to work in 2.2.3 with the 2.2.3.2 client you can add the points in correctly and the gold points inis are in the 2.2.3 files. All you have to do is edit the classes add in the extra skills one or two new maps if you really want to and in the end the rest of the work is just adding in the newer weapons ect into 2.2.3.
I never fully tested compatibility such as damage defense and portals so this is just a possibility that using a 2.2.3 server base might be better off.
