Abandoned Rail map tutorial list

[Skellitor301]

Hi, I wanted to say I enjoy the revamped tutorials but one thing bothers me. In the last mission, abandoned rail base, when completing the game you're given the option to continue playing on the map but when you chose this option you're not given access to any advanced tech to research, like laser turrets to replace the ones lost or accumulators for when the lasers start to fire. Is there a way to make the rest of the tech tree available for this map? I was looking at the save game data and it seems possible but I'm not sure what to add and where to make it work. I'd appreciate any help making this map basically a sandbox as soon as you finish the scripted missions.
