Wiki edits won't save

While trying to save some fairly significant changes to the wiki of Survarium, the text "Whoops, looks like we ran into an error." pops up. I can't apparently save the changes. Hopefully someone responds soon since I still have the thing open in my browser.

You've encountered the Quarterly Bug:

If you want to edit a game with a quarterly date: add the info, then add back the quarterly date (it always disappears when you start editing the page).

I have been having the same problem on the Steam Trading Cards page and am not sure what to do differently to get it to work.

@bobafettjm: The page likely has "too many" associations and the system can't handle trying to save all that info in one edit. I haven't been able to edit the EverQuest page in two years because of this.
