Hi, folks! We're noticing some errors coming through from people trying to create systems that aren't being accepted. If you're trying to make a system and getting errors, especially if you're submitting it repeatedly, please give us details in this thread!
We'd love screenshots of the system you can't submit. Also, if there's something you're doing while editing a system that always causes a problem, that would be a really useful clue for us to fix it, so let us know.
