I am using construction scripts to create my level. I’ve been using 4.14 for a couple of days. However it has freezed on me thrice (once yesterday, when compiling a construction script and twice today while clicking on the map after editing a construction script to see the changes), upping RAM consumption to 99%.
The level is filled with a landscape, but the part where something else is placed (meshes, splines) isn’t too large, 40x30 grid with 1000 uu2 tile size means it’s 40000 uu x 30000 uu. The grid data are in a struct (3 vectors, 2 integers, one bool).
I have already tried to optimize the construction scripts using Instanced Static Meshes and Hierarchical Static Meshes.
How can I roll back to 4.13 to see if issues are related to engine version?
