Hi!
Yes, we’ve noticed this effect right from the beginning, especially in winter.
Unfortunately, we can’t do anything about this I am afraid. Only Asobo can fix that as far as we know.
Frankly, there are many things devs have no influence on. F/e some buildings blend through a fog, snow on aprons is generated automatically etc. 
Plus freezes and CTDs. Please keep in mind, that all products are very well tested by the MS team before publishing and they never encountered any issues with freezes or CTDs. It obviously does not mean that the problem does not exist, it only means that some things just can not be handled by devs (yet). We can only relate to the frustration of some of our customers and sure, if something does not work correctly you should probably demand a refund from the seller.
