Does this work as a bug?

I know my house fire earlier was something normal in minecraft but I did have blocks destroyed by the fire. Only 3 blocks but still

Anyway here is another picture my nether portal that wont go away even though the blocks are destroyed.


I dont know why i built it there i just did and it wont go away now.

From earlier though here is a picture of my fire place I now know that fire can jump through blocks and really far.



It caught the rest of the house on fire which sucked but i just dont use it anymore because of the way fire works even though there are no blocks directly above it my whole house was on fire.

 

Fire spreads.
If there is 1 piece of fire left, it can possibly burn your whole house down.

It's all natural.

 

Before i was unsure of how far fire could spread because it was surrounded by lots of non burning blocks. But this post is more about the nether portal than the fire spread. I wish i had known how far it could spread when i built that fire place. And yes i know fire spreads it should not have destroyed any blocks in my house though on this server.

Not sure if its a bug or not but my mooshroom spawner on my island stopped working after the update as well. it worked fine before the update
