TUFLOW Message 2846
ERROR 2846 - Cannot have multiple "Read GIS Nesting" commands
For builds prior to 2023-03-AA, only a single 2d_qnl layer can be used, i.e. only one “Read GIS Nesting ==” commands in a single .qcf. Multiple 2d_qnl layers can be used from build 2023-03-AA and onwards.
If using a build prior to 2023-03-AA, ensure only one 2d_qnl layer is being read in.
