Custom Battles Don't Load

[GuardianEJ]

I have been trying to start a large battle with like 10v10 but every time I try to it never loads. I tried lowering the ship count to about 5 and it didn't work. I've been using quick start to try and do it but it never works. I'm assuming this is an error on my end but I can't think of the solution, unless it's just too many ships to randomize
