Last Monday I had said that we were hopeful of a release for the patch this week (week of 28th Feb).
Whilst that is still possible, it's now looking very unlikely. We have been chasing a rare and seemingly random crash issue for the last week (memory corruption) that we are struggling to reproduce due to it's randomness, and when it is crashing, it's giving us limited information in tracking it down. We have made progress in narrowing down what is causing it, and working round the clock on this, but tests and test code are still ongoing despite working on it 24/7.
I would therefore suggest that the patch and data update will likely be released next week (week of 8th March), which still fits into the original timeline given if near the start of the week!
I will provide more information once we have more.
