I would suspect a coincidence more than correlation. A lot of people who never experienced CTDs before have been getting them randomly since last patch. I’m one of those people. The only CTDs I’d experienced were from known issues like the VFR map after the Japan update and the Carenado planes. Outside of those known, widespread CTD issues, I never had a single one since this last patch. Now I can have several per day.
I’d recommend keeping the fix in place. If you see regular CTDs, try removing it. But I’d be surprised if this mod was the cause of the crash.
