New MicroSplat version compatibility issue

Does anyone having issue with Microsplat node after updating to newer Microsplat version 3.791? I notice that the Microsplat material & prop data assigned to Microsplat node will auto reset whenever I delete the "map magic game object" in Hierarchy & re-drag the graph back into the scene. I need to assign the material & prop data everytime. This is not happening when I'm still using old Microsplat 3.79. Also, I'm having issue with Microsplat texture exceeding 16 textures. I got below error message - IndexOutOfRangeException. Does anyone have the same issue?
