I have 3 players in an editing session.
All 3 of the players see different memory usage of the island shown in the pictures below.
A problem I also encounter is that the player that initiated the session sees randomly different memory usages. Its a difference around 20000 units on the map I’m testing on. Other maps have different deviations.
@Tim1qaz Thank you for your report! We would like to look into this further, would you be able to submit a bug report using the form available here? Fortnite Creative
