Well, if your problem is that the mobs disappear, then the issue is that the SR_GameServer has reached his max of "Entities" having more than 50 k of mobs. the solution is simple, alter the mobs spawn by this quieres
Code:
USE [SRO_VT_SHARD]
GO
UPDATE dbo.Tab_RefNest SET dwmaxtotalcount = dwmaxtotalcount/2
--Credits to MiDO(RZ)
Code:
USE [SRO_VT_SHARD]
GO
UPDATE dbo.Tab_RefNest SET dwmaxtotalcount = 1 where dwdelaytimemax = '21600' ;
UPDATE Tab_RefNest SET dwMaxTotalCount=1 WHERE dwTacticsID=32100
UPDATE Tab_RefNest SET dwMaxTotalCount=1 WHERE dwTacticsID=32200
UPDATE Tab_RefNest SET dwMaxTotalCount=1 WHERE dwTacticsID=32300
UPDATE Tab_RefNest SET dwMaxTotalCount=1 WHERE dwTacticsID=32400
UPDATE Tab_RefNest SET dwMaxTotalCount=1 WHERE dwTacticsID=32500
UPDATE Tab_RefNest SET dwMaxTotalCount=1 WHERE dwTacticsID=32600
UPDATE Tab_RefNest SET dwMaxTotalCount=1 WHERE dwTacticsID=32700
UPDATE Tab_RefNest SET dwMaxTotalCount=1 WHERE dwTacticsID=32800
it should work(If that are the problem)
