Are there still problem with chunk resets in the Twilight?

[Affex]

As the title says.
I´ve heard of people that has lost everything from quarries to entire bases in the twilight forest due to chunk resets.
Are those problem fixed?

I had this problem twice and then after that it went away without me doing anything. =\

I´ve heard that some people have problems with chunk resets in the nether too.
So I repeat the question, Does these problems still exist?

I've never experienced a chunk reset in the nether or twilight forest, I did have somewhat repeatable chunk reset in a Mystcraft dimension with an ender chest, IC2 Miner, and a chunkloader. But that being said I have experienced a quarry deleting chunk reset in the overworld, as well too. The issue seems to be less about the dimensions then about chunkloading.
