Possible bug

I jumped into a game following someone else so I don't know what server but not PR. It was wild a boomer slap sent survivors flying 100's of feet in the air and when I got to the helicopter it was not there.

The chopper bug is well known... If you fail the finale once it doesn't come back and you have to switch campaigns.

As for the boomers sending you far into the sky I dunno since I wasn't there, but a maxed out boomer slap sometimes sends me really really far away. It's not really consistent with how far away you fly...

 

The gravity was set to 0 or something, I guess you didn't notice everyone jumping so high. I tried telling you in game Vulcan but you left.
