illegal property modification, windslpine

Added a windspline to an island i’m building, modified the slpine point to produce a curved wind tunnel, when attempting to save changes i receive in the message log > editor errors > illegal property modification:
widnslpine
not sure what this means any help would be greatly appreciated

Same here with grind rails. They work fine atm, but modifying a point in the spline will cause UEFN validation errors and lock the project forever.

The way I fixed it is to revert to a previous build where the spline wasn’t modified yet, and them simply existing in the map is fine.

Woah, thats a worry, I shall have to take care updating.

Ah hah so they be spline errors…I did get two of em yesterday on a fairly new map during one save but they went away from the next save. I was using a few road splines, 2 of them use a custom mesh.
