Where is Komal and Shakti?

Have Komal and Shakti vanished into thin air? No mention or anything! What's happened to them?

You are right. I was wondering the same. At least for Komal they made a story that she is gone away to her friends house but no mention of Shakti at all.

Even Meera is missing from the scenes (I don't miss her regardless) but I think the actress has left the show.

I think the actors taking turns disappearing.

Komal back today what a nonchalent reaction to seeing Pratigya alive. I think Komal has come on earth just to get married then bhaad mein jaaye duniya hum bajaye harmonia

Meera isn't missing. She's still there.
