Help - Exiting Precursor Systems *spoilers*

[X10AFreedom]

I am stuck in the precursor system and can't go back to the X220 system in the precursor mission. The artifacts the aliens asked for are already taken out of the ship and the Dialog are all completed and the hit message tell me the portal is open but the portal trigger won't start for some reason.

Anyone else have the same problem? I only got this problem after I installed the Motherships Mod by Goblin Wizard. That is the only changes I made to the game and the trigger worked before the mod.

P. S. The Starhammer memorial also don't drop any loot anymore as well! Tested many times and nothing drop after the Starhammer got destroyed!

Edit: OK, the portal trigger problem is fixed by replacing the precursor location files which I think had some error in it. However the Starhammer memorial still don't drop any loot!
