As you can see here, Clicker Heroes seems pretty broken for some reason - but only in Opera browser.

When I load in Opera, I get greeted with this screen, even though my Flash is up to date. This does not happen in Chrome.

Secondary note; before the "please install flash" screen (but after the refresh to get the 0.17 roll-out), I was unable to click ANYTHING - not to attack, not to level up heroes, not to change tabs, not even the side buttons like the wrench icon or subreddit button. The only way I could restore functionality was to go into the inspect elements menu and close it out. This would restore my ability to do things... until I switched tabs, and then the issue returned.

Like an edjit, I didn't save my progress before refreshing for the new update, so I may have just lost almost a week of progress. Be smart, save your game. Learn from my mistake - you never know when things may just decide to break.

Edit:

Upon inspecting the broken page, there is one error present:
