Tried it on my gungame server. At first, it all seemed fine; however, I had to disable the plugin. The reason is simple, strange server behaviour: knife disappeared for all players; this morning I noticed a bunch of bans with the same reason from HLguard - burst fire detected. I connected to the server and noticed that I don't move normally after the spawn; some stop-and-go rat race
I used the provided plugin without any modifications.
P.S. the server is boosted to 1000 server fps and has HLGuard (speed hack blocker is deactivated). Again, it seemed fine for the first few maps after the plugin start when I was spectating.
