Constantly deleting and rebuilding Tower of Endless Night for a constant +10 culture a turn?

Can that possibly be working as intended? (And for other buildings like this which I haven't tested yet, that also give a chunk of culture points when construction finishes).

It's not hard to get a planet with enough manufacturing power that you could delete and rebuild something like this every single turn, and that just feels... a little wrong? Sure I could choose not to do it, but Culture Points seem designed to be given out in such small amounts everywhere else in the game, that of course I am going to be tempted to abuse something like that.

If it's a bug, thought I should raise it!
