trying to bake complex prefabs causes index out of range error

[erikbaender]

This plugin is amazing, but unfortunately it breaks down when you throw prefabs with a large amount of static components at it:

Assertion failed on expression: 'm_PendingLightmapHashes.size() == m_LightmapCompositeHashes.size()'

IndexOutOfRangeException: Index was outside the bounds of the array.

I already tried playing around with all the available settings like baked / mixed mode and texture size, they don't seem to make a difference. This error always occurs right after baking is finished.
