Not sure if this is the right place to report a possible bug but here goes...
Steps to reproduce:
1. Start with an empty ...\SavedGames\DCS folder (this is just to ensure that it's not some other script and/or mod conflicting)
2. Launch the sim and open the "CREATE FAST MISSION" window.
3. Click "ADVANCED MODE"
4. Click "GENERATE MISSION"
The mission will be generated and can be flown.
Now install this mod in the ...\SavedGames\DCS\Mods\tech folder and repeat steps 2. to 4.
When I do this the mission is not generated and the message "invalid stoi argument" is logged.
