Okay, so I took a deep look at this to see what's going on. The bottom line is that your game is extremely large. The data file for your game is over 25MB...which is about 10x larger than most "big" games. That has nothing to do with the graphics you're using or anything like that, that's just the metadata that says things like "put this graphic here on the page", "this page's name is 'Page One'", etc. So most of the issues you are experiencing (not being able to create a copy of the game, taking forever to load the game, red errors, etc.) are due to that issue. In fact, when I loaded up your game, it was taking up 1.8 GB of memory just for that tab in my browser. So the question becomes -- why is your game so large, and what can we do to help with that? The size is due almost entirely to the Character Attributes part of your game. Because you are using the Pathfinder sheet, and because it uses the new Sheet Worker feature, basically every Character you make in the game comes with a set of "default" attributes. Things like "Your Strength-Mod is X" are calculated the first time you open the sheet. Now that's usually not a big deal, but since you have something like 300 characters (including all of your "Hex" characters), each with those default attributes...you're got tens of thousands of attributes. Most of which are for characters you aren't even using as Characters (like, the character sheet is essentially blank). The bad news is that right now (like Phil said above), even if you archive a Character, we still load in the data for that character (including the attributes). I'll see if there's anything we can do to fix that, which will help with your load time issues, at least. But as far as being able to copy the game, really you're just very much stretching the limits of the system at this point just with the sheet amount of data in your game. I'm going to check in with the Pathfinder folks to see if there is anything we can do to cut down on the number of attributes created for essentially "blank" character sheets, which might help. Anywho, in the short term, I'm afraid there's not a whole lot we can do to help, since the problem is really just the sheet size of the game. In the long term, I will look into those two things and see if we can help. If you want to know what you can do "right away", getting rid of those extra hex Characters by deleting them would definitely help. You could make them Handouts instead, which while it doesn't give you the ability to do the "shift Click to open", would probably drastically speed up your game.
