I am neither against nor for to your opinion. It could could be a visual bug, or may not. In any case there is an obvious problem, which is either a visual bug, or a cheat. Yet, I want to focus on former.
I have been playin this server since 2017, yet this visual bug issue is something new to this and previous launches. Thus, there is an obvious reason for this to occur, that we don't know. Yet, I can not accept that you, as administrators, don't know the reason either.. The gameplay on this game is constructed based on visuals, and I don't think you will against this fact. And, having the visual bugs are not acceptable especially if it is as frequent as this case. As an example, the gameplay of FPS games is also constructed based on visuals. And, if there is high ping, package loss or any other common issue mainly related with user's connection, the game itself does not allow those ppl to play, because it is unfair. You may state that, the connection of user is not something that you can control. Yet, you can easily test and find out the reason when this is happening and what is the cause, and temporarily block these users untill the connection problem is solved, like other games.
Saying this is a possible visual bug case, and implying that you are in the innocent side does not make any sense on my side. If somebody is innocent there, this will be the guy, recording this video. All in all, I am not accusing any body except you guys, who are on the administrative side of this server. You have to solve this visual bug issue, all I can say is this.
