OK, every time I try to make a grifball map i put the 3 capture plates, set 1 to AS_BOMB, and the other 2 to AS_GOAL. when i play a custom game there however, you can pick up the bomb but not score. anyone know why this is?
Are the two AS GOAL plates given red and blue team designations? And is the bomb spawn point set to neutral?
Set them to the team that owns them (spawns on that side). The red goal is where blue wants to plant the bomb, and vice versa.
Easy answer: go play a game of Grifball and save the map you play on. Open it up in forge (using Basic Editing). Look at all the settings on each of the capture plates and any hills that are present. Make your map the same as that. Oh, one more thing. If you are testing in a custom game, you may need one player on each team for the objectives to function properly. I am not 100% sure how this works with assault, but in CTF if you fire up a multi-flag game with just one player, the other team's flag doesn't even spawn. Certain objectives that are tied to a team color require at least one player on that team to be in the game. So maybe that's your issue.
