During this Ritual, when I enter a cave as assassin games takes me back to Geralt and Dethmold, and after quick chat, Geralt asks for one more time.
Dethomold does ritual again and I'm back in the cave, but after I turn right and they start talking it takes me back to Geralt and Dethmold and again, Geralt asks for one more time...
And that loop continue and continue.

I've tried everything
- Let those two assassin finish talking, but as soon I made few steps after first turn on right, Im back with Geralt and Dethmold
- Reloaded game before I killed assassin - no help
- Realoded earlier - no help

Anyone has any tip or knows how to solve this since i cant progress further.

follow the guy leading the way exactly. you must have sprang a trap.

Yep. Thanks a lot

And don't get noticed while sneaking...
