I temporarily patched this to have a fixed value for animations of 230. but its parent mod is https://mods.vintagestory.at/autoatlas. 
This will be taken down at the original modder's request or be deprecated when they update theirs. 
This mod fixed my issue " System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index') at System.Collections.Generic.List`1.get_Item(Int32 index) " "Vintagestory.Client.NoObf.ShapeTesselator.TesselateShapeElement(Int32 indexForLogging, MeshData meshdata, ShapeElement element, TesselationMetaData meta) in VintagestoryLib\Client\Render\Tesselation\ShapeTesselator.cs:line 400 at Vintagestory.Client.NoObf.ShapeTesselator.TesselateShapeElements(MeshData meshdata, ShapeElement[] elements, TesselationMetaData meta) in VintagestoryLib\Client\Render\Tesselation\ShapeTesselator.cs:line 309 at"
