They kinda hit a soft reset button at the end of situation changing episodes, like "Body Parts" where Quark is supposedly broke and without a Ferengi license to do commerce and that doesn't seem to have many consequences either. In fact in the next episode Quark is back to his normal self. The Ferengi license is mentioned later but only as a plot point. That's rather common for DS9. Voyager is worse because it hits the hard reset button, where nothing is ever mentioned ever!!! The ship is half destroyed, like at the end of basics or the micro virus episode and everything is repaired before the end credits!!! Odo is a solid but we barely see the difference... He even has an episode where he links with everybody WHILE BEING A SOLID!!! Anyway, the point is DS9 is not big on consequences.
