Should I remove the bug? Or not?

Hey ya'll! So I was going to purchase this vase thingy? Which cost 160 and I have 471 when suddenly the game exited. And when I open the game again, my in-game money did not lessen and I was able to purchase the vase for FREE! I suspected a bug so I purchased the other stuff and here it is😆 (I'm worried about the bug though, will it break my phone?).
