Fragment of a discussion from Project talk:Terminology gadget/LiquidThreads
I will look into how to solve it, I have noticed it a couple of times myself.
@Xiplus: I think I have solved this problem now. Please let me know if it reoccurs. (I mean: You should no longer get edit conflicts with yourself, but it is still possible to get them if someone else edits the page in the meantime, as is normal elsewhere too.)
