Rename dataclass dumps data

if i rename a dataclass, and i rename it, all the data in the dataclass evaporates.

Hello Mikey!

That’s expected, since the current structure of that updated dataclass does not match the old one.

really? i didn’t restructure it, or rename any attributers. i just renamed the dataclass, itself. i don’t remember 4d doing that when i renamed a table (maybe it did, and i just don’t remember it).
