3 Errors After Importing Unity Package

[joy-1337]

Assets\PumkinsAvatarTools\Scripts\Editor\Data\PumkinsAvatarInfo.cs(8,19): error CS0234: The type or namespace name 'Validation' does not exist in the namespace 'VRC.SDKBase' (are you missing an assembly reference?)

Assets\PumkinsAvatarTools\Scripts\Editor\Data\PumkinsAvatarInfo.cs(9,19): error CS0234: The type or namespace name 'Validation' does not exist in the namespace 'VRC.SDKBase' (are you missing an assembly reference?)

Assets\PumkinsAvatarTools\Scripts\Editor\Data\PumkinsAvatarInfo.cs(17,9): error CS0246: The type or namespace name 'AvatarPerformanceStats' could not be found (are you missing a using directive or an assembly reference?)

Not sure what any of this means, but its keeping me from finishing an avatar, upon importing an older, most likely depreciated version it crashes after exiting PlayMode.

Make sure you're on the latest SDK and unity Unity 2019.4.29f1.
