Sounds like nature is telling you it doesn't want you to live there.

to be fair, if you store the butter right side up, you’ll be ok.

maybe only put a smaller amount out, not the whole brick...use it before it goes bad?

BS, we keep our house temp high throughout the summer (~80F, 26-27C) and I've never had butter go rancid. Keep it away from direct sunlight, keep of covered, and only put out enough for a week or two and it'll be fine.
