tModLoader If I mine blocks above my custom sign in the top-left corner, it doesn't switch from anchortop to anchorbottom style.

[dragon3025]

I have a tile that uses the same TileObjectData as the vanilla sign. While it's in an upper left corner, I mine the block above it and it doesn't change from anchortop to anchorleft style (so it looks like it's hanging in air).

After struggling, I finally just copied all the TileObjectData directly from ExampleCommandSign from the "old" folder. I have a feeling it's outdated because my sign still wont switch from anchortop style to anchorleft when I mine the block above it. Here's my code:
