Hey Andrew, I also experience this bug in 4.8 and it’s great you have shown this workaround here, it seems to work in one direction, but no in the other. So if I have speed set to 0.2 in the editor and then set it to 2 while the game runs and adjust the local rotation of the wind source, it get’s updated, but if I have it set to 2 in the editor and try to set it to 0.2 while the game runs, it does not get updated, wind stays very strong.
