Hi Epic,
There is something wrong with packaged builds & instanced static meshes which are created in a blueprint’s construct script. The server’s network is being saturated if a player comes into contact with one of these instanced meshes.
This is a regression & needs a solution ASAP as it will be affecting a lot of games.
I am using the latest build pulled straight from 4.17 GitHub branch.
Server Log is filled with this when a player comes into contact:
