DE Error: "List Index Out Of Bounds (1767)"

[C4Detonator]

Digital Earthworks is malfunctioning recently and I don't know why this is happening since it has never occurred in the past.
When I'm doing anything in DE, placing objects, doing Splines, or moving, or nothing at all, the object im holding goes in one direction forever or the camra does until I have to exit and restart the program.

A message pops up saying:

List Index Out of Bounds(1767)

*usually the 1767 number is different everytime

I have no idea how to fix it and this error is preventing me from making a track, any info on how to fix it is very helpful.

I am having the same error message pop up, and it is VERY annoying. Sadly, I don't of any fix, but what I do is load another ecosystem file that is empty or only has 1 tree while working within Digital Earthworks, then at export time I swap over to the actual ecosystem file for the track. Although it is annoying when you are still trying to place more trees, but moving the camera around less can help, and the number is just the number of the last tree placed/total number of trees.
