Some games that just disappeared...

Sep 9, 2018
I have been playing here for about 4 months
but last week all of a sudden the usual 'War Games' that I usually play in was gone. I couldn't find it (and it wasn't a computer problem, the other games that DID appear ran smoothly)
now, I do find it but it never ends when the player reaches 100. I just been to a game there which has the 1st spot nearly 600 kills and the second 100.
what happened to these non-customed games?
the Shotty Swords one also disappeared and I don't see it.
What happened here?
Thanks for reading and please answer.
