[2019] Did CAMP build budgets "shrink?"

After Halloween passed, I scrapped all of the decor I had placed down to ensure I would have room for some Christmas stuff once the season came around. Note that i did not build ANYTHING new in my CAMP since Halloween and I had a small yet noticeable gap in the budget bar. Today, I just spent $20 on Atoms to get Holiday decor that I can't even place because my budget is suddenly "exceeded" again despite having not built anything and having nothing in storage. In my confusion, I scrapped one light bulb to see if I could then place down a colored string light, but still could not. However, I also couldn't replace the light bulb I had just gotten rid of as my budget is still "exceeded." While my CAMP weight is pretty high, if I was told correctly, weight and budget are two separate entities that do not affect one another.

Am I just going crazy, or did build budgets spontaneously decrease?
