I do agree that it'd be better if you'd lose any tech gained after building a tech center when it's destroyed, but unfortunately this is an engine limitation and thus can't be changed.

Open AI(E).ini. Then take some taskforce which the AI builds often, I'll use this one as an example:

[075BFDC0-G]
Name=3 Rocket Launcher
0=4,AIMSAM
1=7,AIMTNK
Group=-1

Now, let's say that you want to add the Phase Tank (Rules.ini ID [PTNK]) to GDI and want to make the AI include the PTNK in this attack taskforce. In this case, add a new line for the Phase Tank, starting with the first free number (2 in this case). After that, type = and then the amount of the specific unit type you want the AI to build. After that, type a comma (',') and the internal ID of the unit, for the Phase Tank this is PTNK.

After adding the Phase Tank, it should be like this:

[075BFDC0-G]
Name=3 Rocket Launcher
0=4,AIMSAM
1=7,AIMTNK
2=4,PTNK
Group=-1

The AI would then build 4 Phase Tanks in that taskforce.

In other words, the format for taskforces is:

[TaskforceId]
Name={Taskforce name}
{some number from 0-6}={number of units},{unit ID in Rules.ini}
{some number from 0-6}={number of units},{unit ID in Rules.ini}
...
{some number from 0-6}={number of units},{unit ID in Rules.ini}
Group=-1

Note that you shouldn't make the TaskForces have too many units (especially expensive ones) or you'll mess up the AI.


Yes, unless you also lose your factories in addition to the tech center. If you for example lose your Weapons Factory after losing your Tech Center, and then you build a new Weapons Factory, you won't be able to build high-tech units until you get a new Tech Center. It's like, building a tech center upgrades your factories.
