i just conquered a planet a minute ago, i swer i used 5 planet time vortexes, its still on a peaking colony not a peaked.

i have no proof, took me by surprise

note - i melted the planet right after i invaded

The planet screen is notorious for lagging worse than the rest of the game, try a refresh. Also it is possible that you only had 4 successful clicks on your time vortexes due to the normal game lag.

On a side note, I hope you took it from an inactive or you fluxed it. If the previous owner takes it back all you'll have to show for the limited edition melter is a thank you note...
