To completely delete that buffs need a clean of db HoldAbnormality at PlanetDB_2800 and then restart the server

Code:
INSERT INTO [dbo].[FestivalSeasonInfo]([id], [setId], [festivalId], [startTime], [endTime], [isActive], [status], [isNpcOn], [isObjectOn]) VALUES (1, 0, ID, '2021-02-08 16:02:29.000', '2021-02-10 16:02:29.000', '1', 1, '1', '1');
