The player can be under the map

[fernandosanchez.zk96]

As I can see this is already a topic discussed, but I'm here to put in the table if for somereason this can help to you guys, I will explain the situation.

I was in a middle of a fight with a Kelvin in our base, their was destroying our patron, then when I was dashing down a stairs with Doorman, the Kelvin uses his ultimate with me and I got pushed to the undermap outside the limits

Thanks that I was a Doorman I was able to use the Portals, to escape from that place and go with my team to lose the match like a great partner, but in fact, was a funny bug to discover, hope this information helps you to find out a solution
