My Lands: Black Gem Hunting

Destroy any level 50 Ruins
Objective: destroy 50 Ruins of any levels

1) I haven't seen any "level 50 ruins" - do they go that high
2) "any levels" It won't let me attack any ruins lower than my rank.

Is there a bug or just a poorly worded quest?
Thank you.

u can buy or get it as quest reward (to attack ruins of all ranks)
You can also kill 3* while youa re only 2* too

and sjut kill 50 ruins of any level

A comma would fix it

"Destroy any level, 50 ruins" Or even better "Destroy 50 ruins of any level"

It just means destroy 50 ruins, doesn't matter what level they are.
