I made a custom builder. Looking at how the SCV builder works, I made buttons, a build ability with about 20 of my buildings in it, and attached it to the builders abilities and command card.All the buildings show up on the command card fine and they can be built by the builder when the game is running, but for some reason they are created instantly. I changed the "Info - Time" for each building, but that didn't seem to do anything.
When I substituted in a command center for one of my custom made buildings in "Info - Unit", the command center built in 10 seconds (the time I had). So it seems it's the actual buildings causing the issues, and not the ability (maybe). I assumed it had something to do with Unitconstruction or unitbirth in the actor's events for the building, but I have no idea which event might impact that.
I have a duplicated "Terran construction" as the actor for the build ability, so I thought that was the cause (like it only impacted terran buildings or something), but
no buildings (duplicated from terran, zerg, or protoss buildings) have build times. They are all created instantly.
None.

I do stuff and thingies... Try widening and reducing the number of small nooks and crannies to correct the problem.
You have to add the ability "Under construction" to the unit's abilities.
Found it, thanks. Fixed the issue. (it's "build in progress" tho)
None.
