Solved'n'fixed bug reports / Re: Unfair death due to extremely rapid ice melting

I did check the snow depth in the morning to get a feel for how much longer skis were needed, and I'd expect the elements to wear off the snow first and the ice after that, once the insulating snow layer is gone, as the melting from below is rather limited. Once the snow turns into slush it ought to eat into the ice, making it brittle.
It is supposed to work about that. But I just checked the source code, and I think you are right: there was a small logic error which causes a bug potential.
The way it is supposed to work is that the thickness of snow cover slows down the ice melting rate in warm temperatures. In some conditions those checks fail, making the ice melt quicker than intended. Sorry about that, and thank you for pointing this out! We will fix this for the next stable version release.

the water temperature should not be affected at all before the ice is gone,
That is how it works. I also checked that, no bug potential there - it is coded in such a way that the water temperature can rise above zero celcius only after all the ice is gone.
The ice thickness it tracked millimetre by millimetre, hour by hour. So that means that in a warm sunny day the ice can be safe at sunrise, but become dangerously thin after the high noon, and be safe again in the night when the temperature drops. That is how it is in real life, too. And every year a few Finnish people drown because they fail to estimate the ice thickness correctly. Well, but yes - I take your suggestions as valid suggestions; it would be wise to have a bit more ice-related feedback. I'll talk about this with Sami.
