I believe Wurst 7.55.1 update was rushed on patching minor bugs that led to Killaura not working properly. When I downloaded 7.55.1, 97% of Killaura hits weren't being registered in a simple sword duel and I assumed it was because of the anti cheat. But when I downloaded 7.55 version, the hits were being registered in the same server I was having issue in operating 7.55.1's killaura module. I would be grateful if devs look into it.
