Ok, a few updates.

I spent 9 hours and reconfigured my PC to get FF14 onto C, and surprise, it didn't fix it, in fact, it crashes more often now. After running a few days like this, then getting the 7.2 update, and running a few more days, the issue persists.

Again, SE apparently has no interest in solutions or reading, giving me the same set of excuses, including asking for yet another reinstall, which I did, with no change. Even their 'last ditch' option of changing the process to high priority in the task manager did not help.

Over 6 weeks now and no change to the issue. And nothing from SE here. Does anyone know if this would qualify as an 'in-game' bug so it can go in the bug forum? This is defiantly screwy and I am almost out of patience.
