Specific Forge map keeps disconnecting

So, I spent 30-40ish hours on a forge map and finally got it to a place where I want to start play testing with friends. Game loads fine, but whenever the game ends, and sometimes at random, all our screens just go black and nothing happens. This does not happen on the only other map I have forged, so my question is: is my mapped bugged or is it custom games that’s the problem? The only thing I can think of is that my new map is a bit bigger (At least scale wise. And by scale, it’s considerably bigger.) than the one that works, and I would just like to know if this is an issue that patches will resolve or something I need to fix. Thanks to anyone who can help.
