Alright, so it only occurs 1 in 3 times (based on trial and error of about 4 different tests of 3, it occurred more than that sometimes)

Anyways -

You can play it to see for yourself here:

*Resize Browser window for best experience*

I made it how it is for a reason its mostly for mobile, but I also am adding this to my other project soon...

Anyways back to the issue, I can only assume the score is there it just isn't being displayed. I have a score multiplier of 10, but this occurred even without the multiplier.

Ideas/Suggestions on a fix is helpful (not in a rush its a side project)
