Ok, so I changed the layout of the TEC research tree.
it is supposed to go from
RESEARCHSUBJECT_HULLTECH0 - pos [0,0]
RESEARCHSUBJECT_HULLTECH1 - pos [1,0]
RESEARCHSUBJECT_HULLTECH2 - pos [2,0]
RESEARCHSUBJECT_HULLTECH3 - pos [3,0]* <My new one that i was planning to add

How do i addd such a thing? I put it in GameInfo folder when i finished it and add lines to the entity.manifest files but when i launch up game it is not there ? what am I doing wrong??
