Adamantite/Platinum Ores not spawning after beating all Mechanical bosses

It says beat all 3 bosses to spawn the ores and Adamantite/Platinum specifically after the 2nd boss but none appeared and no text showed up. Tried the single player method and didn’t work either.

Hard to progress without Adamantite/Platinum forge. pls speed i need dis. There’s very rare encounters of this which lead me to post this. Idk what to do been up all night tryna figure it out.

I am playing multiplayer with friends and following the boss list properly.

I can’t remember all the mods I downloaded but here are the ones I remember:

Calamity mods

Melee effects

Vein Miner

Magic Storage

NPC someting

Boss Checklist

Recipe something

Wikithis

A vfx mod

Pets
