17:32:32.663: Warning: [Upgrade] Using backward-compatible build settings. The latest version of UE sets the following values by default, which may require code changes:
17:32:32.663: Warning: [Upgrade]     WindowsPlatform.bStrictInlineConformance = true        => Updates MSVC inline conformance (Remove unreferenced COMDAT) to true (Previously: false).

17:32:32.663: Warning: [Upgrade] Suppress this message by setting 'DefaultBuildSettings = BuildSettingsVersion.V6;' in RPGGameEditor.Target.cs, and explicitly overriding settings that differ from the new defaults.

17:32:32.663: Warning: [Upgrade]
17:32:32.663: Warning: [Upgrade] Using backward-compatible include order. The latest version of UE has changed the order of includes, which may require code changes. The current setting is:
17:32:32.663: Warning: [Upgrade]     IncludeOrderVersion = EngineIncludeOrderVersion.Unreal5_6
17:32:32.663: Warning: [Upgrade] Suppress this message by setting 'IncludeOrderVersion = EngineIncludeOrderVersion.Unreal5_7;' in RPGGameEditor.Target.cs.
17:32:32.663: Warning: [Upgrade] Alternatively you can set this to 'EngineIncludeOrderVersion.Latest' to always use the latest include order. This will potentially cause compile errors when integrating new versions of the engine.

17:32:32.772: RPGGameEditor modifies the values of properties: [ UndefinedIdentifierWarningLevel: Off != Error ]. This is not allowed, as RPGGameEditor has build products in common with UnrealEditor.
17:32:32.772: Remove the modified setting, change RPGGameEditor to use a unique build environment by setting 'BuildEnvironment = TargetBuildEnvironment.Unique;' in the RPGGameEditorTarget constructor, or set bOverrideBuildEnvironment = true to force this setting on.
