Mobile Is this area eligible for spawning crimson key mold?

This area is auto corrupted after hard mode. I've defeated over 100 pirate invasions here and still didn't get any crimson key molds. I've already got 4 jungle key molds and 2 hallow key molds just on the way getting here

If you’re getting crimson enemies like herplings (as shown in your pic) it should be a viable spot for the crimson key mold to drop. Sounds like extremely bad luck, sorry.

If you have another crimson area that you can try in, maybe give that a shot just for a change of pace.
