mission.sqm, line 0 in ARMA 3 - MISSION EDITING & SCRIPTING Posted November 29, 2018 mission.sqm is being preprocessed on every load/save. Errors in possibly included files could cause that error, not only mission.sqm itself. Also, just in case, make sure all your included files end with a newline. Some end with a line having a #define, e.g. #define IDC_PROGRESSBAR_TEXT 200 but not having a newline at the end of file. This file being #include'd will eat up the next line after #include. So in the end it might look like #define WORLD_CENTER getArray (configFile >> "CfgWorlds" >> worldName >> "centerPosition")version=53; Not having explicit #includes in mission.sqm does not mean the preprocessing is not done on other files.
