What is the latest UE4.25 random number seeding method in C++?

[Nanotyranus]

Hello, I’m currently having difficulties with updating my project to UE4.25, with the following error message:

The project could not be compiled. Would you like to open it in Visual Studio?

[Upgrade]

[Upgrade] Using backward-compatible build settings. The latest version of UE4 sets the following values by default, which may require code changes:

[Upgrade] bLegacyPublicIncludePaths = false => Omits subfolders from public include paths to reduce compiler command line length. (Previously: true).

[Upgrade] ShadowVariableWarningLevel = WarningLevel.Error => Treats shadowed variable warnings as errors. (Previously: WarningLevel.Warning).

[Upgrade] PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs => Set in build.cs files to enables IWYU-style PCH model. See Include What You Use (IWYU) for Unreal Engine Programming | Unreal Engine 5.3 Documentation. (Previously: PCHUsageMode.UseSharedPCHs).

[Upgrade] Suppress this message by setting ‘DefaultBuildSettings = BuildSettingsVersion.V2;’ in SauroborosProtCEditor.Target.cs, and explicitly overriding settings that differ from the new defaults.

After looking at the UE4.25 patch notes, there does seem to be some changes related to random number generation, so the random number seed srand does seem like it could be the crux of the problem. It’s in the format-
void srand(int32 LevelSeed);
with int32 LevelSeed being a blueprint input.

I’ve had a look for if there’s anything been said as the solution, but no luck so far. Anyone got any ideas, or if I’m looking at the wrong issue to finish the update process manually?
