Flow restructure Crashes when set to a custom resolution

I already submitted a crash report about this but I think Il reiterate it here.
So I’m using the flow restructure node on a 40km by 80km (4096 by 8192) project to create some sort of sloping base for my terrain, the thing is I want to make the base at a lower resolution so that it doesn’t take so much time to iterate and it doesn’t take up large amounts of RAM. However, flow restructure crashes when it is on custom resolutions


The flow restucture in the group crashes when building.
I sent this file to some other people and they had it crash as well.
I have attached the TMD for replication (forums does not allow dump file uploads)
