I had 1 cat left to find but had 2 sections unfinished. I finally used the HINT to get the last cat and when the game finished with fireworks the second section with the fencing and guards (assuming it is Buckingham Palace) was left uncolored. https://steamoss.com/sharedfiles/filedetails/?id=3373869230...

Just purchased this game and I am unable to finish the level that you unlock all of the bonus stuff from. I see the people I need to click, but nothing happens when I click them.

Ate to play on win 10 did not seem to find any problems. If there are problems with Normal mode on win 8.1: it is not passable, it writes about the arrival of a train with cats and problems with the menu begin (you can’t exit, restart, etc. Exit ONLY through a forced alt+f4 termination)....

EDIT: After testing, bonus content for all games except HC in London is unlocked when special cats are found. Being online is not required. I suspect that HC London is not working correctly due to my being offline (which means that I never get Steam achievements). Devs, please fix HC in London so that the bonus content can be accessed by offline players. Thank you so much! I'll leave my initial post below. ====== Does the bonus content require being online for the unlock to actually work? ...

Found all cats in Advanced: https://imgur.com/a/JtZDg3X Achievement did not unlock. I did use some hints. Last cat I found was Rita Oreo, if that matters.
