Either I've gone mad or I'm about to.. How do I change the time it takes for a building to be constructed?

In the info field of the ability.
The time you set there should be the building time of the specified unit/building.

Ah, didn't see you could scroll down there. Another question. When I add, copy or duplicate a unit, the copy doesn't get all the assets, the main model most significantly, and I can't seem to add it in either.

Duplication feature is broken because it doesn't set all the links properly (especially it fails with the actor).

To repair the actor, go to the actor, set the unit token to your unit. Then go into the events and change the unit everywhere the old one appears.
Make sure you are memorizing what was behind the unit name like "start" or "finish" because that gets deleted.

edit:
But because that is broken, you learn a little bit how actor events work. They are like tiny triggers.

It's happening, I'm going mad!

Is there no other way? The copy will be 99% identical, so I don't really need to duplicate, doesn't matter if it shares assets with the original.

A new unit should have its own actor in most cases.

You could try to use the xml view. Maybe it makes it easier to change.

Most of the stuff don't have any tokens, how do I add them?

Tokens are just text replacements. It is intended to be like a variable for editor usage.

You can change the token or change all wrong references. But the token can be buggy, too, as seen as when it become "none" after duplicating.

You need to change all references by yourself, then. At least I'm sure that the actor events need to be corrected, some other fields may be ok.

I'm lost, I think we need to switch to baby language..

I've gotten about half way by double clicking on various things in the bottom left box ("object explorer"). Now I'm out of things to click on, and there's still stuff missing in there.

Which unit are you trying to duplicate?

The object explorer shows most of the connections with other data objects.

Probe. The model and portrait are working, the sound is not, rest I don't know.

The unit's sound, if you give commands is set in the unit's actor.
Combat and ability sounds are inside other actors.

Thanks, gotten a bit further. I've set construction times to a few sec and now the "warping in" animation doesn't play, so I need to speed it up and have it start almost immediately. Should I do that in the object editor or with triggers?

unit's actor -> actor events -> something at the top (construction) I think is used for warp ins.

Which unit? The buildings? I still have the regular probe which does regular warp ins, so don't think I can mess with that.

Every animation is can be controlled with actors as they are started by actors.
You just need to find the correct actor and modify/add the correct events.

The Nexus actor has the model in question, but there is no mention of it in the events, and no mention in the xml code. The animplay in events is called "ConstructionDeath", which a) makes no sense, and b) seems completely taken out of thin air, and I still have the original problem of not being able to tell which probe made the building.
