Multiplayer level streamed assets mess up leg animation/foot IK

[EonZeNx]

I'm using dynamic level instancing in a multiplayer game. Level streaming is not supported for multiplayer so I implemented a seed-based RNG level creator, making each instance of the game load the same level instances.

The problem is the legs mess up and spin in circles for all non-owned client when standing on a level streamed surface. It all works perfectly when I placed a large cube in the persistent level, but it breaks every time I step off onto a streamed asset.

Some experimenting reveals that even with blueprints parented to both the ALS Base character & the ALS Character results in the same behavior.

Wondering if there's any way to fix this?
