Hello everyone, Today I encountered an error with the xml file, an error is shown in the debug:

[23-02-25 18:05:30] WARNING: [gameplay]/drag/drag_s.lua:413: Unable to read XML file database.xml @ 'xmlLoadFile' [Line 0: Error document empty.]
[23-02-25 18:05:30] WARNING: [gameplay]/drag/drag_s.lua:440: Unable to read XML file database.xml @ 'xmlLoadFile' [Line 0: Error document empty.]

The database.xml file is empty
