I am also getting a similar(same?) error when I try to move assets related to my main spline object (error attached as well) error log

Hi mdsf,

Your crash is definitely interesting. Can you update to 4.7.4 and see if you’re still getting the same crash? It does seem to be directly related to your use of splines. Do you see this crash in any projects that do not contain splines?

Thanks very much!
