[pi-msr]

How to Reproduce:

1. Create unicorns by clicking on the 'unikitty' image.
2. Then click on unicorns and create more unicorns.
3. Then click on the 'unikitty' image again until the 'angry unikitty' (/img/unikitty2.png) appears.
4. Click unikitty image again to start creating unicorns again.
5. Unicorn count start from where it left off and not again from 0.

• Once all the unicorns are cleared and started again the count should be correct.
