We haven't been updating the legacy theme, in terms of code, new game data whatsoever. and further enhancements with our codebase won't reflect into legacy. Even if we let it say, you will see that error. What can we do but just remove it.

It's not like we removed it in a whim. If we plan to make it stay, additional effort will have to be exerted in our part, which I did not go for. If other developers are willing to, they can update the legacy and fix the bugs and I will re-enable it from settings.
