Heya :) Since you've been editing a lot around here lately, I wanted to make sure that you knew about upcoming changes to Don't Starve's infoboxes. I've opened a discussion in the forums and would love to hear your opinions there. Please feel free to stop by!
As a rollback, you are granted with rollback right and comment delete comment right. However, some rollbacks tell me that they cannot delete inappropriate comments. Thus I have created a testing account User:Mentalbot and I discover the problem.
I have contacted Wikia Staff, here is their response:
Unfortunately, this seems to be a bug and not something I can fix instantly. I have filed a ticket with our engineering team to handle this request. I will update you when I hear more from them.
So guys, let wait and I hope everyone can continue to fight against vandalism :)
