More prizes awarded

Hi

I have a scenario whereby more prizes are being awarded than available.
For example if I set quantity of 100 prizes I sometimes see 102 prizes awarded.

Based on my test the issue seems to be a race condition of sorts.
For example If two users spin the wheel simultaneoulsy and they both win a prize then only 1 of the prizes quantities is reduced.
I was able to replicate this scenario in a staging environment.

I am using ersion 1.3.0. I don’t want to update this due to my wordpress environment.

Can you please assist with a fix?

Thanks
