Now a note on how a wiki works so folks can have an understanding of what is going on. Think of it like saving a spread sheet. 3 people are in a new wiki and it’s blank, all 3 are in a version that has no data and they each open up a draft to edit. The first person saves in spot 1.
The first person saving updated the wiki but it does not update the draft copies that the other 2 have open. Now the second person that saves puts their name in spot 5 but all other spots are blank on their draft version so when they save it replaces spot one with a blank.
Now the third person puts their name on spot 2. When they save their draft version only has them on slot 2 and all other spots are blank so it changes spot 5 to a blank as that’s what the draft version they are saving shows.
Because each person had a blank draft open and that draft is not affected by what is done to the wiki in real time it will kill all updates done to the actual wiki while they had their draft open.
A bit long winded I know but I am hoping that will help folks understand why the overwriting happens.
