### Summary As soon as I launch a memory calculation I get editor disconnected and it just sits waiting for the memory calc to start which it never does. I tried the solution here which has worked before but now it doesn’t do anything : [Memory Calculation - Editor keeps disconnecting - #15 by Midtrex](https://forums.unrealengine.com/t/memory-calculation-editor-keeps-disconnecting/1298808/15) It does seem to start the memory calc if I use that work around and says its starting but it just stays on 0% We can’t push any updates to the published island anymore because no version will memory calc. Latest private code I’ve tried to memory calc 2498-5964-6802 (public code 2129-6965-9065) Any ideas please? ### Please select what you are reporting on: Unreal Editor for Fortnite ### What Type of Bug are you experiencing?

Same here. On my map after clickcing Memory Calc editor disconnects and I need to start session again in order to Memory start calculation. Just dont close Lunching memory calculatin in UEFN at bottom right corner. This methoid works for my map. But yeah, frustrating experience. ---
