Can't mine Mythril even with more than enough pickaxe power? Is my world corrupted?

[Fused Zamasu]

I have a hardmode world and for some reason I can't mine mythril or titanium, it's indestructible. This is a huge inconvenience since one I can't progress and two some of it generated in my house and destroyed part of it. I even used an all items world to "cheat" myself in a vortex drill, but I still can't mine it. For some reason the mythril and titanium appeared instantly after I killed WoF. If someone could help, that'd be great!

Try to remove the mods one by one, unsure which one is causing the issue.

I know calamity mod changes how hardmode ores behave, although I believe it just makes it so certain hardmode ores don't spawn until you kill mechanical bosses
not entirely sure what would be causing this but you could look in calamity's settings if you haven't already
