Based on the diary entries, I formed the opinion that the stove operated in such a way that there was always, even at night, an on-call person watching it. It is mentioned several times in the diary who is on duty. There is also an accident related to a fire, when someone's coat catches fire, there is also a picture of this and the incident is mentioned in a diary without details (Zina)

If the pieces of wood found in the tent were used as the insulating material for pushing the stove's chimney pipe through the fabric of the tent, then there is no firewood in the tent. If the wood was not insulation, then where are the insulating asbestos rings? I don't understand why they don't have firewood? They could bring it with them They left 50 kilograms of equipment in the labaz, there was room for firewood for the stove in the backpacks! But it wouldn't have been enough to melt snow and cook outside the tent! Just for the stove! But it is very conceivable that Gyatlov was also unsure that the tent set up in the snowfield would be stable enough to install the stove in the stormy wind, and he thought, as I think, that it would not be. And that's exactly why they didn't bring firewood at all. However, from the fact that the stove was taken, we have to conclude that he did not want to go on the ridge, but wanted to return to the forest strip. Otherwise, they could have left the stove in the labaz - although that would have been too reckless!
An interesting aspect that has not yet been discussed! February 1 is the first time that the team has to set up the tent outside the trees. They had already spent several nights in the tent during their journey, but the tent was always set up among the trees. Setting up in the snow field is happening for the first time! There could be problems with that! It is not routine how many skis will be at the bottom now, how many are needed to fix the tent, etc. If there was some established method of who did what in the process of setting up the tent, then it could not necessarily be used here. It is also conceivable that there were those who now see this tent set up on a snow field for the first time.
An important question is what causes the center and one end of the tent to collapse? This can happen if the skis and ski poles pierced in the snow, with which the tent is fixed, move in the snow. Or so that the tensioning ropes break!
Why is there no information on whether the tension ropes were broken or not? Presumably, there is no information about this because they were not broken and no one thought it important to write it down! It would have been important! Or could the cutting of the fabric of the tent have caused the loosening in the fastening system that causes the tent to collapse? How is the order? Does the tent collapse first and they cut themselves out or do they cut through the side of the tent first for some reason and it collapses because of that? Hm?
If you leave the tent somewhere in stormy weather, it is advisable to knock it down and load it with something so that the wind does not take it away! Of course, in a situation where they can't even put on their clothes, they obviously didn't spend time knocking down or loading the tent! There was no tent left empty, there were their backpacks and all their equipment. Although a tent with split sides is used as a sail by stormy winds.
In the settlement of Vizhay, which is ~50 km away, strong winds were registered that night. The reference to the extreme cold is not. But from our point of view, from the point of view of the snow tracks, the primary one is the question of snowfall now, that is, how much snow fell during the days of February 1-2? Of course, wind and temperature are also important! If the “local residents” as @Osi mentioned remembered the cold and not the snow, probably no significant snow fell then!
