App Issue / Question

Is there a size limit on a module? I mean, can a module have too many maps, tokens, handouts and / or characters to run properly?

There are a couple sizes that can cause issues. Page wise: the big one is individual page size - anything over 100x100 is problematic (Roll20 gives you a warning at 50x50 I believe). Related to page size: Maps should be uploaded as a single image - having a large number of tokens/map tiles/drawings will slow down the map. The above page issues occur when you are on that page. Additionally, having a large number of characters (in the several hundred range) will slow the game as well. I'm not aware of any issues with number of players.

Thank you Scott. I made a very large campaign and ran into loading problems.  I am hoping it was just issues with some of the individual's browsers.
