Curious how this will affect our progress for those of us still working on exploring.

For example I nearly finished exploring Act 5 Chapter 3, only have two paths left on Quest 1(Act 5.3.1) and then will have 100% explored Act 5 Chapter 3. With the changes will my progress reset to only having gone through this quest once or will it remain where I am at?



Just curious as I'd like to know if I need to burn through those last two paths to 100% Act 5 Ch 3 before the new update to ensure my progress not lost. If someone knows please share with me.
