Problems with custom games (and forge)

I’ve just finished a new map called “Tilt Table”. When forging it and testing it in custom games, I’ve noticed several bugs with Halo 5.
I’ll list them below to see if anyone has any work around for them, but if not then if someone could direct me to the bug report forum (I assume there is one) then I’d be very grateful.
I will put a link to a video or image of the problem (unfortunately my Waypoint rank doesn’t allow me to post working hyperlinks yet, sorry).

If you wish to take a look at the map, you can find it here:

Many thanks in advance for any help.
