Hello all, I’ve investigated the cause of this issue using verse scene graph custom items & inventory experimental support to dump the player inventory state.

We know the issue occurs on calling Load() on a save point device (it does not matter if there is any existing save). After loading the save and overwriting the player’s inventory, they can no longer build when using Simple Build.

Dumping the player’s inventory state when they have Simple Build disabled vs enabled, we can see they have proxy items to represent the target build to place.
For “Regular Build” they have BuildingItemData_Wall, BuildingItemData_Floor, BuildingItemData_Stair_W and BuildingItemData_RoofS. For Simple Build they have BID_SimpleBuild_AltBox2 and BID_SimpleBuild_AltWall.

After calling Load() on a save point device, “Regular Build” players will retain all proxy items listed above, *but Simple Build players will have BID_SimpleBuild_AltBox2 and BID_SimpleBuild_AltWallremoved from their inventory.
I assume the current bug behavior is due to save point device not properly restoring these Simple Build proxy items.

Thank you for your attention to this matter.
