This problem is still present today. If I select all players, and start the sim with clear skies and in sim change it to live weather, then it works ok.
Only problem with this solution is, that I cannot use the “Live Players” option at all which would be something I would like to use.
I have a feeling that Asobo is not very interested in fixing this problem which is odd because live traffic and weather are 2 main points on this sim. Where can I post a bug about this or is there a bug report about this already. My sim is up to date.
