Collision Detection in FF6LE

In my case, I edited the dinner table at Gestahl's banquet. Due to my re-arrangement of that story segment, I needed 9 chairs instead of 10, so I deleted the right-most chair and shifted the remaining 4 over by 1 space. That was apparently enough to break things.

When you say byte 17, is that decimal or hexadecimal?

EDIT: Nevermind. In both decimal and hexadecimal, the byte is the same. Looks like I'm seeing something different.
