For some time I have problems with saving to main hard drive.
I am absolutely positive that no other file is opened and it happens to various files.
Hello - are you using Grasshopper with a Hops component? If so, please update Hops via PackageManager.
-Pascal
Installed? YES
Using? NOT YET
It seems Hops affected saving without droping it into GH canvas. Seems to be working fine now.
Thanks
