Same question here, how long does it take for artifact to recharge?  or is it one time thing.

@Gauntlet I noticed that many of them you can build like a project after fully upgraded over an over again giving one continued bonus's, (which I like), however, some of them such as, Chimirac Biomass (which terriforms an additional tile) does not.  Trying to find out if that's a bug or if being able to continue to build them as a project is a bug.  I personally would love the continued use of them.

Edit: Another one is Arnor Embers Complex (Increases attack of selected fleet)

Additional thoughts on this is if they aren't meant to keep allowing use, then the artifact tile should just simply disappear after the artifact is maxed out.  No sense using up space on the artifact screen if they can't ever be re-used?

Yeah you can destroy them, my main question is, why allow it for some artifacts but not others.  And I don't think it's unbalanced as all players, including AI should be able to use them.  Solution: to your point making it broken though, is to have a counter on each upgrade, such as the first time costs x resources, next counter causes that to double, then next causes to double that ect... or just simply adding x resources times the number of counters used ect...  therefore it would keep getting more difficult to upgrading, allowing you to continue but, just keeps making it more expensive each time.

I would still like to see them do a pass on bazaar ships, as right now it's not worth purchasing the high end ships as by the time one gets to the level of unlocking them, one can build ships much more superior to them.  With the exception of some special ones.

I understand a lot of this most likely could be modded, however, the base game, without mods, shouldn't require mods to be balanced or work uniform throughout.  With that being said I do appreciate your suggestion.  Any @stardock person able to answer the question about artifacts?  Maybe I'll just post it on discord.
