Error and massive lag - PlusEMU Habboon

[HabbixDK]

_{Hey guys so i'm just playing around with PlusEMU on my own pc with a few friends on it, however sometimes i'll get this error and then a massive lag will occur on my hotel, anyone know a solution for this?:}

Error in query:
REPLACE INTO `user_achievements` VALUES ('2678', @group, '5', '1050')
System.InvalidOperationException: Connection must be valid and open.

Probally because a wrong setup. PlusEmu should work without any issues/lag but it's just the setup.

REPLACE INTO `user_achievements` VALUES ('2678', @group, '5', '1050')

@group hasn't been defined, it seems. Find it where it gets executed from and then define it correctly.
