That’s because users made a record 406 edits in the temple flo sign up wiki, all in a very short period of time.
Users crashed the wiki, and rather than waiting for the system to respond, continued making edit attempts after the wiki access was overloaded.
406 edits for 150 sign up positions- more than double the number of positions available. That’s a lot of mistakes and edit conflict overwrites, most of it within the first few hours.
Compare that to the cobra lips sign up, which has a reasonable 207 edits, and went perfectly smoothly because people did their best to follow the rules.
That makes it pretty clear what the problem was. This should address any lingering confusion you may have @ColeLennon.
