trough does not get created when table is imported.

[shntat]

Trough is missing when table is imported. Have to add manually. trough does eject but fails to eject after ball is drained.

We'll have a more complete example table with proper assets and maintained functionality at some point, but right now we're not there yet.

If there is a bug with the trough in general, we need more precise repro steps.
