The issue is outlined here, but this post is a year old.
I have tried everything, and I can’t get it to work. 2 of my computers aren’t working. And it’s only on this place. Even all the scripts removed still has the issue.
It works fine in StartServer, nothing else. Re-installing did nothing. We already tried clearing the place but it has some dependencies that would take quite a while to work around.
EDIT: Even when downloading a local copy, the issue persists.
EDIT 2: I just got my friend who is directing our work to try to use Play Solo, did not load. The issue is within the place.
