File:Entiyt 639.png

I was playing survival in my normal minecraft world. While collecting wood, I noticed a sign. I went near the sign. The sign was spammed with 'ENTITY639'. Thinking my friend was cheating on me, I called him. He told me he was trying to sleep and wanted me not to disturb him. I found this logical because it was 12 am. Then, when I got home, I opened the chest to put the wood in the chest. The inside of the chest was full of bedrock. I looked at my other chests and they were all the same. Then I noticed something in front of my house door. When I went to my house, I saw a sign. The sign said HOW FOR YOUR LIFE, and when I turned my back, I saw it for 1 second. ENTITY 639. After this incident, I could not enter minecaraf again. I always encountered an error called ERORENTITY639.
