Forge 2 Strong 4 Halo

So I was gonna make a cool pirate ship battle, two ships docking each other, symmetrical map, and even a cool off map area for the entey with a skull and cross bones with burning eyes, and the only way to make it complete is the stormy winds and dark night effect, so I messed with the Overwrite and I kept crashing Halo 5 lol, anyone else have simular problems? Where would we even report these things to 343i?
