Nodes have been broken for a couple years now, At least for me. Clicking on the link brings you to a broken page and the only way you can adjust a node is if you happen to know the link to it. You can't make new nodes at all and there is also a memory leak (I assume) that causes the whole page to lock up if you edit too much or leave the page open for too long, making it unable to save changes and losing everything you changed. It's the main reason I never got around to finishing my geo guide or making more.
Wait, broken how? Which link? They've always worked for me.
The crash from keeping an editing session open too long: I've known it was an issue but no one ever complains about it so I haven't taken a deep dive into what's making it churn memory.
Anyway, can I have some details on which links, and what you mean by "broken"? Again, they work for me, so I need an idea of where to start looking.
[Edit: Just was able to create one from my test account without admin rights, so I really do need a better idea of what you mean by "broken".]
