I played FAF beta, should be the lastest version (automatic update).
The UEF T3 Fabricator, if linked to 1 T2 power, cost 2100; if linked to 1 T2 and 1 T3 power, cost 2400... This is not reasonable and should be a bug I think.
[Also, it seems the Fabricator did not benefit from the nearby mass storage. I'm not sure this is the new setting in FAF beta or it is also a bug.]---- this has been solved, work correctly.
Sorry I cannot upload the picture as it was too large.
Hope anybody could test it and see whether this is a bug.
Thank you.
