Boss Spawned Inside of Player House

I was really excited to finally build a tiny refrigerator next to my big one, and then the Roc(???) boss's shadow loomed from what I assumed was a special effect from a window to insinuate it was outside waiting to kill me

I thought, "Oh! That's super cool and terrifying!" and ran outside to maybe lure it away, but it wasn't outside at all

It was only in my house, and I kinda' figured it's a bug & maybe it won't actually spawn and kill me, but it spawned and killed me

I think he didn't agree with having a second refrigerator

My recording software didn't want to work, but I got the end results in a quick gif: https://gyazo.com/b12014bf49cea849a99eb21485d4947a

Hope this gets somewhat fixed!
