Can not get over a lot of snow-drifts on the road any more

[Skywatcher]

Since the update to v301 (or possibly already since the "Timberwolf Mountain" update, i have not been playing in between those) my character can not get over a lot of snow-drifts (heaps of snow) on the roads anymore. I get stuck be behind them and have to navigate around them. They are not particularly high, approximately 2 feet high. Before these posed no problem at all. I have noticed it has become harder (or impossible) to climb certain slopes any more, which i understand as you could climb hills that were almost impossible to climb in real life, but it seems to be that the adjustments have been a little to big, causing this issue with the snow-drifts.
