This is based on the development version 1.97.146039.
I tried to change the threat level as described here https://community.bistudio.com/wiki/Arma_3_CBRN.
When i execute the code the first time i get a messageBox with the info "Shape \a3\UI_F_Contact\Data\Objects\ChemicalDetector_01_ui_F.p3d not found"
The threat level gets changed nevertheless.
