Eyelash mat broke since 4.17 nothing but Engine Version changed.

I have a question. Since 4.17 the eyelashes for a model I have have been broke but nothing has changed to the textures or mat. Am I missing something implemented after 4.17? It’s a an old and now “dead” Mixamo Fuse 1.3 character but it’s only his eyelashes giving me any issues. I have 3 screenshots/ In game mode, the Mat and in the Mesh Viewer
