Below is a list of things that the UCP may affect on this wiki, and how to fix them (if possible):
Mainpage slider - The main page slider, on UCP, will only show the text on UCP when you hover over it with the mouse. This can be fixed, but Fandom guidance suggests not using sliders as viewers aren't viewing hidden content. Showcasing one thing rather than many may gain more traction. A fix is available though and please let me know if you still want that.
Wiki activity - Wiki Activity won't to be present on UCP, but this script can be added to enable a version of this. Please let me know if you want a hand with that.
This is all I could see that would outright not work properly. As ever though, unforeseen issues may arise, and please feel free to message me about those. This wiki should behave similar to how Unsolved Mysteries Wiki has been behaving on UCP.
Please comment below if you have any more questions, or find any issues. :)
