Good day everyone just wanted to know why I can’t play egglocke using manually generated eggs but i can play it on randomized eggs.
this error appears when i start
Don’t do it, don’t generate your own. 
I am on a Mac and having the exact same problem. This seems to be a different error than the one where adding the missing data file fixes the issue. The eggs are definitely not illegal because I have tried a few different variations just to make sure and it is always the same thing.
If the “data” folder is missing, that could be causing your problem. Try putting this folder into your game’s main directory.
I had issues until i put this file in there. Should look like this.
Hope this helps.
Thank you so much! it works! 
This worked! Thank you!
The only thing I will say is that I did have to cut down on the number of available eggs in the text file in order for it to work. When I first attempted to load the game with the egg file, I got the “script is taking too long” error. I went from over 100 eggs to just the 4 I really wanted to use, and no longer had an issue. I am not sure what the exact limit is, but I am might play around with it to see how many I can get to load successfully.
Thanks again!
