Server Name: 1020
Mods: =MODS=


Bug Description:

The UE4-Conan Sandbox Game has crashed and will close Fatal error: [File:C:\B\tech_exiles\code\Engine\Source\Runtime\CoreUObject\Private\Serialization\AsyncLoading.cpp] [Line: 6738] LoadPackageAsync failed to begin to load a package BP_Event_SiptahStormspawns_ELW because the supplied package name was neither a valid long package name nor a filename of a map within a content folder: "


Bug Reproduction:

When loading onto the server, when the interface is loading, the game crashes with a fatal error

I’m not the only one with this problem, many who play on the official PVE server #1020 have the same problem when approaching the city of Sepermere

Seems that encounters continue to cause issues.
