I haven't seen this mentioned anywhere, but are you able to install 2 different types of augments in a body location?
I have 5 bone lacing in the first bone slot and I would like to install a few marrow batteries in the second bone slot so I can try out some powered things. However, even though the GUI shows 8 pairs of red & blue slots, I cannot place the batteries into the other slots. Also, if I have the batteries installed, I can't install the lacing. It just pulses the existing mod red. I am at 73/100 tolerance left and the items do not say that are incompatible. Am I missing something? I would think you could shove as much stuff in a slot as you have tolerance for and that the additional slots indicate that would be so.

Hmm, it seems those cyber augments are exclusive. I was able to get 2 different eye mods to work.
