I found a way around the freezing and losing progress... every 3 or 4 levels I quit out to the title screen and refresh the page! That way if it does freeze (which it seems to have stopped doing since I started my 'technique') I don't lose multiple levels of progress. Getting into the 50s and then having to start from Level 1 again TWICE was a tad irksome :P
Every time I get into the 50s (between levels 51 and 57 so far) it freezes the game, then freezes Firefox! I have to force quit, and when I go back to the game all my progress is lost :(
For people complaining that the chat room isn't loading, as far as I'm aware it will never load as it's been removed... and there's probably no point reporting the game not loading or missing BOTD as Kong sacked all the staff that would deal with that... great times! :P
I come back to the game to finally get the missing THREE challenges completed for the Hard Badge, only to find my progress has been wiped and I now need to get ALL the challenges as I can't remember which ones I missed previously :/
I've played this game MANY times, and today is the first time I realised I could select and apply artefacts!!! I feel like a proper numpty! And it did make the game easier to complete :D
I'm going to have to start taking a screenshot EVERY time I complete a badged game! I had to go through undead mode twice to get to the end screen so I could report the missing badge as I didn't know it wasn't going to register the first time :/
Daily puzzle works today! So I tried the trick of changing the date back to do the missing ones, but it didn't work! I think it's because they were never actually registered as 'uploaded' so they are now gone forever... or at least till next year when the 2020 pack is released :P
