[BUG] Barycenter bug

[Plutonium]

Object property window disappears visually but the fields are live and the hints come out and the values can be changed (blindly).

To reproduce:
Open>Lands of Ice and Fire>create a barycentre between the stars>deselect everything>right click on the barycentre>   the UI disappears until I select an object then it comes back, but the object property window stays invisible.

Same here, except it does this on all other simulations without applying the barycenter.

The barycenter tools are very much a work-in-progress, and it seems like there are definitely some bugs with them right now. Thanks for pointing this out, Plutonium.

Fridog, I'm not sure what you mean. Are you having issues with the interface disappearing even when you're not using barycenters?
