For the Attack/Armor upgrades, did you try both kinds?
Thank you, this worked. I did what you suggested and added both the armor and attack upgrades manually and it seems to work: https://imgur.com/Wk6g1gd
But shouldn't the ' Tech Tree -Disable tech tree restrictions for player 1' allow everything?
EDIT: It seems some of the mission events are overriding this. I was testing on Toshe's mineral harvest mission, where the reapers are first introduced. (ttosh01) Everything seems to work fine at first, but when the trigger that introduced the reapers happens, all upgrades above lvl1 disappear from the Engineering bay.
For the Raven, you could try Allow/Disallow ability for player, and choose Starport - Build Raven ability.
Thank you, this definitely works.
I'd like to figure out what I did that allowed the Raven to be built in the first place. Btw, This problem also occurs with Ghost and Specters. Is there a way that I could build both Ravens and Science Vessels and Ghost and Specters with a trigger without changing the Data of the Barracks and Factory?
Also, what I'm doing is basically a mod. But when I tried to do a mod I didn't find a way to test it with the campaign maps. Is it possible to play campaign missions with mods?
