After one of the server crashes this week, I found that my Slime kill count has gone down. I noticed this because I attack Slime on two characters (at the same time) and found that one of the kill counts were higher than the other. Hopefully you guys have some type of history that records how many times we killed Slime so you can check this particular case out. I am almost 100% sure that I attacked Slime on both characters and that both had an equal share of kills. If needed, I will provide any additional information to conduct the search!
About 2 days ago we had a freeze mid-slime which resulted in many people missing a kill being added to their counter. We manually spawned another one right after the server came back as compensation for those who hadn't gotten their kill saved. This even happened to me as well
