Watch towers and watch tower failure

[Ry Vor]

Any insight to the lack of watching done by the aforementioned towers? Especially if an L4?

I thought I did answer that.  May not detect Concealed emissaries.  At L4, it would not fail against non-hidden, but at hidden it would be like L1 against non-hidden.

The part about them not always working as intended?.

Watchtower should be just as an L4 agent doing recon in that area.   I'm not sure if the code gives a 5% chance of failure to detect Ambushing as an L1 would have on normal recon.
