I activated the Cursed Earth ritual at night, in the open. Then I placed a torch, and apparently the cursed earth hated me forever... I thought that it wasn't supposed to burn in the presence of artificial light. I did manage to save about half of it, which was still a lot, though.
I installed Reika's Void Monster mod. Then I forgot I installed it and was quite literally freaked out when I got close to bedrock. I still am sometimes... it sounds so close.
I always put my resources away when I think I don't need them, and then I need them the very next minute.
In one of my previous worlds, I found TWO hungry nodes. By accident.
The first time, I didn't realize it, because I was just walking by, saw an "interesting" cave in a Pasture biome, passed by and... was thrown into the air and died from falling.
When I went back, I morphed into a chicken so I wouldn't take fall damage, so that I could get close enough to mine my gravestone. I barely made it back alive...
The second hungry node was found in much the same way as the first, except that it was in a Lavender Fields biome. Same story, except that I died right underneath the node, causing all my items to be dumped into a grave directly underneath the node. Back to chicken morph... I couldn't mine the gravestone, so I tried destroying the node. It apparently didn't like that, and killed me again through damaging me, creating another gravestone directly on top of the first. I had lost all my items at this point. Needless to say...
