Where did the issue occur? In a match
Which part of the map or menu were you in? If you don't remember the exact name, please describe the area or what you were trying to do in the menu. This was persistent the whole match
What were you doing when the issue occurred? E.g. respawning a squad mate at a beacon, using an ability, a squad mate left the game. This started when the game loaded in I believe, right before character select
Did your squad mates also experience the issue? Yes
How many matches had you played in a row before the issue occurred? 3
When did this happen? (dd.mm.yy hh:mm) 13.04.19 3.00 CST
How often does the bug occur? Rarely (0% - 9%)
How severe is your issue? Major impacts to gameplay
What happens when the bug occurs? The Apex logo appears twice before the character select screen, the second time looked like I was going to time out of the match. I noticed the input seemed delayed on when choosing a legend but nothing else. After the game has started the match was slowed down considerably. Movement, melee attacks, and some guns were slowed down. I have a clip of the match here for reference. I can make a clip of the full match if needed (we didn't last long). https://plays.tv/video/5cb23ff0c2fa50728f/drunken-brawler-simulator
What should be happening instead? Normal gamespeed
Steps: How can we find the bug ourselves? The first sign that this has occured to me was the logo appearing twice before character select and the odd input delay at character select. Otherwise, nothing before hand suggested something different has happened to cause this, as all the players seemed affected.

Here's a video of the bug itself, seems everyone in the match was affected.

There was a strange Apex logo appearing twice before the match began at the character select screen, followed by a weird input delay to pick a legend. Afterwards, the game ran at a very slow speed for everyone. It felt like an old school Unreal Tournament mutator was turned on in the match and causing everything to go slow including movement, melee, and some guns.
