@anon50268670,
Create a new topic with a title of “Excessive Icing Effect Needs Reworked” (or something like that) in #bugs-and-issues:weather of this icing effect. Make a reference to this topic (in resolved bugs) that the effect needs to be re-worked:
https://forums.flightsimulator.com/t/excessive-icing-effect/266397
Also, I have just merged several duplicate topics regarding the ON/OFF not saving. Please use this topic:
https://forums.flightsimulator.com/t/icing-bug-back-turning-off-still-shows-visible-ice/432882
I don’t want to move this topic into Bugs & Issues as there are multiple issues when one of them already has a bug topic.
