Disallowed Object - Physdata Foliage has ruined all of my projects (UEFN)

Hello,

Over the last several days every single on of my UEFN projects has been ruined by this one issue - Found disallowed object type /Game/Balance/Physics/Materials/PhysData_Foliage.PhysData_Foliage

It occurs at random after saving a project and attempting to start a session, and once it’s happened the entire project is ruined - no amount of deleting the broken asset fixes this issue. You have to start from scratch.

My friend has this issue too. It’s gotten to a point where we don’t want to continue using UEFN because we know that our work means essentially nothing.

Please fix!!
