Siege Golem bug

So I’m in Chapter 4, and I’m working my way through the War Zone. Found the siege golems and - contrary to what the walkthrough and the NPC’s told me - they were destructible in a head-to-head fight, even if prolonged. After I destroyed the golems, I killed the wizards.

The problem is that I found out that I can’t complete the quest now for some reason. So now I’m stuck trying to figure out what script is necessary to update the quest to complete it upon dialogue, and then putting in the name of that script under the “dm_runscript” command or whatever it was called.

The bigger problem is that I can’t view the script with the toolset, because the genius developers saw it fit to not allow players to access the chapters through the toolset if you haven’t completed them first.

This game has been nothing short of a headache from start to finish.

Does somebody know the name of the script needed, or failing that, another way to fix this problem?

Edit: Nevermind, I fixed it.

For some reason, the variable for the number of golems killed was stuck at 1. Managed to set it to 2 instead.

Edit #2: Also I managed to import Chapter 4 into the toolset manually. Didn’t think of that at first, would’ve doubted it even if I did.
