Known Issues in 2018.4.24f1

• Animation: Animator.Update CPU time spikes when multiple animations are playing (1184690)

• Asset Importers: Crash on VertexDeclarationD3D11::GetInputLayout when importing a broken FBX file (1239074)

• Cloth: Cloth has graphical artifacts when an object moves out of the camera (1254174)

• Mono: Crash on buffer_add_value_full when debugging with code editor attached (1249172)

• Package Manager: Immutable packages altered by the API Updater are reverted to their original state when packages are resolved, which can lead to slower import performance in that context.

• Shuriken: Crash on CreateDirect3D11SurfaceFromDXGISurface when calling DrawRenderer with a Trail Renderer (1216216)

• macOS: If the Android Tools are not installed through the Hub, macOS 10.15 (Catalina) default security settings will prevent the Android NDK binaries being executed. These settings have to be changed or a signed Android NDK (r16b) will be needed to build Android. More information here: https://developer.android.com/ndk/downloads/older_releases.
