Removing Residential Rental Glitch *endless loading*

I updated each world with new houses & everything. Each world I built an apartment in, afterwards I dealt with the "Neighboring Houses show as Default/Empty" glitch & with help from "pessyl92" I was able to fix the empty lots issue but now Im trying to figure ot how I can delete those lots anytime I try I get endless loading, I even did the gallery method & it didnt work. Is there a way to get rid of those lots?
