WordPress AitTheme (Expedition Theme) Tour Map Input Limit

I'm assisting in development of a WordPress based site using the 'Expedition Theme' available from this site: http://ift.tt/1NEUoFv

Within the theme is the ability to add a map (Google Maps API) with input points on it to create a path. Each input point draws a map line from pointer to pointer to create the path, and each input point can be assigned a marker, information, etc. The issue I've run into is that at around 152 map marker inputs, no more inputs can be added to the map. When I press 'Update' to save and view my changes, it kicks me back to the dashboard, and all inputs past 152 have been removed. No error messages are generated and no errors appear in the console. I've tried this on a few different maps, and run into the same problem each time. I've also searched through the code for any sort of hard-coded limits, but didn't find any.

I know this questions is linked to this specific theme, but has anyone else come across this type of map issue with a WordPress theme?
