Issues and Bug Reporting

Summary

This project is a tycoon game. A verse device named TycoonManager manages a base of around 3000 actors using an array of 500 indexes of a Basic_Buyable class, used to manage the tycoon base. With one base, the island memory is 75k.

This is intended to be a multiplayer game. In order to create a second tycoon base, the actors and the device are duplicated. Once duplicated, a live edit session is launched to check functionality and memory, and all was working as intended and memory was at 78k.

This process was done for the third base. However upon launching a live edit session, the validating local content step takes around 1 hour and 30 minutes, and after completing, a live edit session is not launched because UEFN has logged me out.

To get around these long validating local content times that log out UEFN and stop me from launching a session, an array is modified in all 3 verse devices, and a session is launched. This causes the validating local content time to be SIGNIFICANTLY faster. However, once in the live-edit pregame lobby, the map never launches due to a cook error.

Live Edit

Steps to Reproduce

Have TycoonManager device with 500 indexes of a buyable class and a base with 3k actors.

Launch session to ensure functionality and memory for 1 base.

Step 2. Duplicate for a second base, and again check functionality and memory.

Step 3: Duplicate for a third base and launch. LONG validating local content times will be observed and you will not be able to launch.

Step 4: Modify one element in all 3 verse devices and launch.

Expected Result

After duplicating 3 times i am expecting to get into a live edit session with a memory around 80k.

Observed Result

Insanely long validating local content times that time out my UEFN connection to epic servers or a cooking error occurs.
