Boss fight causes connection interrupted??

Provide a clear explanation with screenshots or video.

Open dealing the supposed final blow to boss, Ultra ♥♥♥♥, the game will lose connection and freeze.
Final blow dealt with double packed minigun Kermit's Shredder (blast furnace).
Like normal connection losses player maintains control for a few seconds while the world freezes.

I believe the problem is Kermit's Shredder, I just defeated boss without it without disconnecting.
I probably won't test anymore but that's a starting point I hope that helps.

Thank you for your input MonkeyMan1. This helps.

Edit: I killed them and it crashed hahaha

Oh this actually helps a ♥♥♥♥ tonne, explains the random crashes people sometimes get!

hey i forgot to record the incident but there was this one time i was playing with my cousin (split screen) and we got the heavenly toilet went into it and the boss fight just ended we went back out with the new stalls and everything but the ultra ♥♥♥♥ health bar was still there it was really weird i thought i would just let you know

You can be downed while "Ascending" Just happened to me on R26

Playing on Geforce Now, Boss fight: I cannot see the Ultra Poop and its minion poop, only the water effect around the poop boss and flying birds

if i try to play the map it closes my bo3

The connection interrupted after killing Ultra ♥♥♥♥ is still happening. Any updates on the bug fix?

wunderwaffe does not work. it can shoot but it will not connect to the zombies and instead acts like a raygun

i cant download it, it says missing files. its probobly a easy fix but i dont use steam to much so some help would be amazing

still getting connection interrupted once killing boss. i'm seeing that this bug is going back almost a year ago? will there be a fix to this? this is one of the maps i actually enjoy! it's a shame i didn't get to see what happens after!?
