Steps to Reproduce

1. Player 2 abruptly leaves the mission in level 1
2. Player 1 completes level 1 solo
3. Player 1 waits in the level 2 game modifier selection
4. Player 2 rejoins the game and selects a game modifier with player 1

Explanation

My PC had crashed during the first level. I needed to restart, but game was still ongoing through host with Cooper (originally a 2 player game reduced to 1 player.)

I was able to hop back in in between level 1 and level 2 and make a selection with the host for the epic gem, but mobs were twice as hard to kill.

When i got back in, I had no weapons or tools of any kind. Ammo supply did not give me anything. I was only able to select a new weapon through the toolbox once we earned it.

When getting the XP upgrades, the host and I were desynced. Our selections would not appear for the opposite player and we had to wait out the timeclock. Once the timer was over, it would make a Health Reward selection for us instead.

However, we noticed that we were still getting Cooper upgrade selections while in multiplayer mode. Before forgoing the match, we were able to select our own upgrades by selecting our upgrades first, then Coopers.

We tried to die to end the match in level 2. When we were both dead, the game waited for a non-existent Cooper to revive us. Host ended up aborting mission.
