problem:

When i research this tech, the engine is unavailable. Can't be found under any tab or in search. Is this just a place holder icon that's been left there?

I think this is a part from USI MKS - best to post this in its own thread over in the mods section.

Probably a problem with the Community Tech Tree

[mcwaffles2003]

ok, im dumb, the engine isnt searchable and was under rovers...

 

thanks for the input guys
