The mini map shows "No Image Found" if I enable the complex map. It works well setting False. I have installed Image Library and GDI+ in Linux. According to the oxide logs, some errors occurred.

Failed to call hook 'OnServerInitialized' on plugin 'LustyMap v2.1.39' (ArgumentException: A null reference or invalid value was found [GDI+ status: InvalidParameter])
