TwistedLincoln I also have the same problem internittently. I haven't found a way to consistently fix it.

Sometimes, if it's a large number of objects I'm copying, it's just a matter of waiting 10,20 30s between copying and pasting. Other times the pasting just doesn't want to work regardless - and you can kinda confirm this on the target model you want to paste into by looking at the Edit menu to see if the "Paste" option is enabled or greyed out.

Just now I seem to have resolved the issue (this time) by separately closing/re-opening each model. [url=https://geodash.org/]geo dash[/url]

BTW, drag/drop furniture objects between models doesn't work for me.

I'm running SH3D v7.5 on Win11
