Trainer is up to date, working, not crashing when loading, and tested 100% working as of 11:00 EST December 3.
Make sure you are using the trainer OFFLINE in PRIVATE where you are the HOST.
For NO RELOAD, leave OFF until you are in the mission and have reloaded and have ammo in the chamber.
Maybe the anticheat systen is that you can no longer send survivors on missions after activating the trainer. At least this is what i noticed.
Have you checked the game version to the trainer?
