Talk:Evil biomes

Hi there! just got through a discussion over at Talk:Corruption regarding whether backwall blocks can spread corruption (or crimson as the case may be). The user in question was kinda-confident that walls could only corrupt other walls, and not foreground blocks (unclear whether that could invalidate housing), but didn't affirmatively know the answer, and wasn't about to add it to the actual page, so I thought I'd cross-reference it here in hopes someone with more code-knowledge/experience would be able to help. Thanks.208.89.33.43 16:07, 16 August 2019 (UTC)
 * I found this thread on the forums that confirms walls do not spread biomes. ;-)  In general, the forums are a good place to look for "dirty details", there's a lot of experienced players posting there.  --MentalMouse42 (talk) 04:46, 17 August 2019 (UTC)
