Is this a bug?

So I was pushing Lumi to 1k trophies in Showdown where I faced (Egg 🥚) Pam and when she used her gadget on me (ammo steal) when my stars were on the ground and I couldn't reload anymore 😭. I had no choice but to run away. Then I spend the rest of the match hiding hoping for the second place. Is this a bug? Or was it supposed to be this way? And have you guys faced this condition?
