Hey,
sorry to hear that. Its a game bug 
Sadly if there was no ID (and I also can’t find anything called like that), so the structure was officialy also never spawned, there is not much we can do right now besides hoping the devs can fix it.
Everything else is just too much work to do for everyone . We can only restore ships that were spawned by the game in some way.
If this is nearly all you had and a really really big loss, let me know. Otherwise we would have to sadly pass on this one.
