Kuleman black cathedral bug

Hi I got extremely exhausted with the way in which Kuleman's black cathedral just lagged for me.

He killed me 30 times when i closed the game because of unnatural lag up to even 15 sec (15000 ms was shown at the top right when i pressed F1) and not only that.
I died after returning the ring and then the game seemed to completely bug out. Kuleman hat no healpool and I have no idea if I was ever getting close to killing him at any time during my wasted 40minutes of life.

the worst is, i tried to get back in, just in case the lag got better and Kuleman's black cathedral was closed to me now.

This is extremely frustrating that in a map where you have to be on your toes nearly every fraction of a second, that it just kicked me out and wasted time.

I would like to get a replacement invitation because you can check the logs of the lag if you wish.
