I can still see many of validates error. Its that much I'm starting to consider them as wasted time...

Is some plan to fix it?

Yes.

There's some code we've developed to detect NaN and restart the optimizer to go down a new path automatically. It's queued up for the release after this current one we're trying to roll out So not 9.90, but 9.91 (9.89 was what we rolled out to test and had to pull back due to errors two weeks ago due to unforeseen errors).

So you have no reason to believe me, considering how slow things have been progressing recently due to work, school, and family demands over the past two months (should be getting better starting next week), but I hope to have a solution to at least the majority of NaNs within a few weeks.
