RF_Transactional

This is one of the object flags. I don't know what it does or what it's for. The official documentation is literary Object is transactional. which gives no additional informaiton. The Transactions section of the official documentation talk about undo/redo so perhas transactional objects are those that store old states in the undo history? https://docs.unrealengine.com/en-US/BlueprintAPI/Transactions/index.html

I the Unreal Slackers discorde I saw the following comment

// not sure what this is but it's named "/Temp/Untitled" and only has the RF_Transactional object flag
// indicates that we're in the editor (and not in PIE either)
if (Outer->GetFlags() == RF_Transactional)

which would mean that we should set the RF_Transactional flag on objects we create while we're editing in the Editor and not setting the flag in Play mode.
