This question already has an answer here:
I've completely rebuilt my base in a Forest Biome from the ground up since the release of the 1.2 update. And when my base was the same as in my old world, and most of the npc's were there (except the hardmode npc's), I thought it was time to activate hardmode.
The first thing I noticed is that I couldn't place any of the new npc's in my house because it was corrupt. Apperently this was because the crimson was under my house going from top to down. So I needed to move my house to another Forest Biome. But the Crimson is spreading really fast!
But how long will it take before the Crimson will have corrupted every green bit of my world? Or should I just place a block of stone to stop it? Is there even a way to stop it? I could always build it in the ice biome. But I find the constant visible falling snow annyoing. I already tried the obvious: purification powder. But the Crimson is just keep coming back!
What would you do?
Once I've made a new world, this time in a floating island (so no form of biomes will reach it), and was transfering some of my items (including NPC room furniture), I saw what was wrong all this time: I forgot to place a few walls!
I don't know if this was causing the
This house is invalid error. But at least this was a possible reason.
Thanks for all the suggestions and sorry for wasting your time. Have an Ale on me!
