Got this error several times in this battle. I had just raided two identical teams prior and used the same attack sequence. The first couple errors, on restart, brought me to the beginning of the battle. The last two brought me to the middle of the battle and immediately errored again.
This is the point it errored at. I have a short video of this but don’t know how to upload it.
My offer still stands. I will ship you a box of duct tape, staples and super glue to patch the code with.
