Tree Sapling Generator breaking GLTF export

I’m finding that when I use the Tree Sapling Generator plugin, the tree will display properly on it’s own but as soon as I introduce other objects the scene will start acting weird and not displaying correctly or not at all! (I am using shared hosting on GoDaddy)

I am assuming in this case the plugin needs to be updated but an not sure how to do that or how to contact the person who made it to ask if an update is possible to fix it. It happens in both 2.79 and 2.80, 2.80rc1 and 2.80rc2.

If anyone has any ideas on how I can get around this then that would be awesome – I was thinking something along the lines of exporting the mesh created by the Tree Sapling Generator and then importing it back in again so it doesn’t store whatever data was generated by the plugin but even then I am not sure how to go about doing this either.

I have got it working ONCE* with the plugin tree mesh and another rock in the scene but most of the time it just doesn’t load or displays with objects missing in the scene.

Any ideas where I am going wrong? Or how I am able to make it work sometimes and not at other times??
