Sometime button only works cleaning the cache

Hello!

I’ve been using your plugin in the last days in my website and i’ve set a list of achievement linked to the ID of different buttons.

Problem is: some button triggers the achievement and some don’t. To make the broken button work i need to clean completely the cache of the browser, then they work again.

Can you help me to understand how to fix this problem?

thank you so much! Hope you’ll reply soon as i’ll have an event this saturday and i don’t know how to fix this by myself!
