Contemplative tombs broke the quest. (Pine)

Came to the cave at the kV and I was impatient to get back, and now I can't get there (no interaction with the input) because the first phase kV counted, then it is necessary to explore the cave itself. Tried relog, secid, TP, saves before this is not done, only AutoSave after exiting the cave, in the folder with the old saves there. Please help, almost completed the game, it's a shame :(
