The houses are working normally in 1.2. I also have the 1.23 and it also works. Are you sure these bugs are not a result of patching the patch to a false original rom. Have you tried patching to the EU or Japan rom. The patch might be updated but not the patching info. So if the patch is updated, but not the info, you might think to patch to the US version and get these bugs, but maybe the patch was meant for Japan rom. I can't remember if I tested the patching to other roms in 1.3 version.
