I believe it is something to do with splines in the project

Somehow the points in a spline component are corrupted. Looks like it stores rotations locations and scales of all points in separate arrays and checks to make sure they’re the same size (which they’re not for some reason).

Ahh i assume this is because of how i imported the splines from 3DS Max, I used this plugin

https://forums.unrealengine.com/development-discussion/content-creation/1597781-export-splines-from-3dsmax-to-unreal-here-s-a-script-for-you

I will look at alternate ways to get these splines into UE4

It seems that we have encountered a similar problem.

I created a blueprint class containing a spline component and placed it in two maps. Afterwards, I edited the spline in each map separately, resulting in the two spline having different numbers of points.

During debugging, I found that the number of points on both sides of the equal sign in the error message exactly matched the values of the actor in the two maps.

Therefore, I modified the spline in the blueprint class to keep the actor in both maps consistent with it, and the problem no longer occurred.

Sorry for the bump but could you share the details on how you solved the issue if you still remember? I seem to be in the same boat as you.
