Aight, for those who have DM comm Errors, this is how you fix it :
DB COMM error says 'Deadlock, lock has turned on another ID/subject'
meaning 2 diffrent Options are trying to reach 1 option, and adventually crash your server, i've been searching for weeks to solve this issue and it turns out pretty easy.
DELETE ALL AH's INGAME ( AH NPCS )
everything starting with :
NPC_auction u shall delete.
how to test iam not lieing? :
press with 2 accounts / or a friend on 'search' multiple time, and it will crash.
so here it is, delete the NPCs ( ah ) and you'll be 100% save from the crashes.
Also dont forget to push the thanks button
