PrefabsUtility does not contain ...

[shills]

Hello!

I just bought Curvy Splines 8 and imported it into my project. So far so good!

I then added the Converter for Unity Spline package, but it did not compile as there is an error:

Library\PackageCache\com.unity.splines@2.6.1\Editor\Utilities\SplineCacheUtility.cs(24,27): error CS0117: 'PrefabUtility' does not contain a definition for 'prefabInstanceReverting'

Which is that statement in the SplineCacheUtility class :

Code:

#if UNITY_2022_3_OR_NEWER
            PrefabUtility.prefabInstanceReverting += _ => ClearAllCache();
#else

Any idea what is the problem?

Curvy Splines 8 version → 8.11.0
Converter For Unity Splines version → 1.3.2
Unity Project version → 2022.3.18f1
Splines version → 2.6.1

Thanks!
