FISM meshes disapearing in 4.18

Development World Creation

Custom FISM components will remove foliage from editor view when the component is compiled.

Steps to reproduce:

  1. Create new child blueprint component inheriting from Foliage Instanced Static Mesh
  2. Paint some Foliage Type onto the landscape which uses this component.
  3. Compile the component.

Switching the Foliage type asset to any other component will undo this issue, and the meshes still work within play mode.

NOTE the component doesn’t need any changes to be made, simply clicking “compile” will cause the issue.
