Hi!
After I did buy Mercinery DLC the Genereic tech tree disapeared and in its place a second terran tech tree was shown.
I can select both and start a game, and it will work with out any problems.
The error is still there after I have emptied the mods folder and deselected the mod option.
Pre Mercinery DLC I did play with 1.6 patch and it worked fine.
After Mercinery DLC I tried the beta 1.6.1 patch and the error was still there.
I have looked at both TerranTechDefs.xml and TechDefs.xml and I cant find any problem with them.
I have the 1.5 version on backup and the only thing that had changed was some new tags.
Regards
