No Existing Sandbox found.

A few days ago, my API's (on Jumpgate) stopped working mid-session. I've tried restarting the sandbox multiple times but i just keep getting this error?

Hi WylRonbins0n! That is odd, since most of the scripts look pretty standard. In the off chance that you are navigating to game and to mod page by bookmarks, have you confirmed that the mod page is referring to the game you are in? (which must be running, in order to load scripts). You can check by opening the mod scripts page from the link on the home page, or by comparing the game identifier number on the URL. If the mod page is indeed correct, try deleting cache and cookies, then log out of Roll20 and then back in.

I once had an issue with the sandboxes loading - I did not have the download scripts error, but I found changing to Experimental sandbox, and restarting, then switching back to default and restarting fixed the problem.

Having the same issue, and also a different one at the same time. made a copy of my game including the api scripts. one game is saying  no existing sandbox. the other is freaking out about fetch. at this point I am severely crippled on running my game and pulling my hair out in frustration. Any help would be appreciated. 

Some suggestions: 1. In the game with the fetch problem, try uninstalling and re-installing fetch. When you re-install, check your list for multiple copies of dependencies. I've run into that a couple of times. 2. Try deleting cache and cookies, log out of Roll20 altogether and then back in.

ok. I've tried 1) uninstalling all APIs and reinstalling all the ones i need.  2) uninstalling and only reinstalling the metascript toolbox.  3)deleting and reinstalling only fetch 4)deleting and reinstalling fetch and the prompted dependencies 5) cleared cache and cookies throughout each of these/ logged out and back in 6) making a copy of the game and not copying over api scripts and installing just the toolbox. still having problems.  I'm not a tech wizard, if by checking my "list" you mean the list of api's at the top of my api library (pic below) then yes. I have verified there are no duplicates. 

Also tried the switching between experimental and default sandbox / restarting. 

ok, I may not be a tech wizard, but i am pretty good with google. Thanks for helping me cause the solution I found was from past/ present you. I was trying to see if there was more to finding duplicates and see what you meant by that. I came across this post <a href="https://app.roll20.net/forum/post/12719268/scriptlet-duplicate-finder" rel="nofollow">https://app.roll20.net/forum/post/12719268/scriptlet-duplicate-finder</a> &nbsp;and tried out your script. found a few duplicate characters. fixed that and for now (fingers crossed/ knock on wood) it seems to be working. You are a lifesaver. I can't tell you the number of times I have been banging my head against the wall trying to get something to work in roll20 and found you had already answered the questions somewhere else.&nbsp;
