My problem is that when I copy-paste objects in Twinmotion it completely freezes my machine, and only a forced restart brings things all together, excepting unsaved data. It also brings another huge problem. After adding terrain it takes around 7-10 min just to save, to prevent from losing files. I am so happy about the improvements of the program but the stability is soo soo bad.
If it helps my main laptop specs are i9 11950H, RTX A4000 8GB, 32GB RAM, Thinkpad p15 gen2; so I am sure the specs are not a problem.
