I need 18.5k carats before the end of the Creek banner

~3.5k will come from the goldship event
~1.5k from team race promotions if I don't shit the bed or the thresholds don't massively inflate
~1k maybe from missions
~500 if I watch remaining main story episodes
~150 if I watch some remaining uma stories
+150 from the current spring celebration
+150 if I grind out the 5m goldship fans
~150 from login bonuses
~300 from trophies maybe if I really prioritize them
~50 from random team race rewards

That still leaves me ~12k short. At least 10k if I'm forgetting something or somehow do a LOT more missions than expected in a couple of weeks
That's nowhere near enough
What the fuck do I do
