Double Battle Error

Hey guys. This is a small bug that doesn't really do much in the game it just brings up this error message when you have two trainers in a double battle and one trainer still has a pokemon to be sent out when the other one is defeated. Any help?

Hi guys, Is there anyone that could help me with this bug? It happens when there is a single pokemon left in a double battle that still has turns to attack.

Here is a video showing the error. Im using 16.2

Nevermind, I fixed it. It was an issue with one of Venom12's scripts I used.
