One of the things I enjoy in second life as flying around looking a the land. I cruse around high enough not to run into privacy barriers.
To stop bumping in to barriers I now have to go to a hight whare the ground is obscured by clouds.... I also need a flight assist.
I accept 15 m was possibly to low... but anything more than 50m realy stops the fun flying...
Regards Jonathan.
P.S. It would have been nice to know this change was coming, and to have been able to comment before it was introduced.
