PCG system not updating when I move splines around

HI all!

I have developed a PCG forest system, that has been working, for the most part, wonderfully.

I have implemented a couple of extra systems that are controlled by splines - paths that can run through the forest, and a closed spline area that defines forest clearings.

I’ve been noticing just occasionally the forest PCG ends up getting kinda locked up, where if I move a path or forest spline around the scattered forest meshes (trees, bushes, ferns etc) are no longer updating. It looks like the generation points in the PCG update, but the static meshes aren’t destroyed and recreated in the new location.

I’m on 5.4 right now.

Any ideas on how to force regen the system? The Force Regen button doesn’t help.

Thanks!

I have seen this as well. If you simply toggle some bools (any of them) on / off in the get spline node it updates them. It’s bizarre
