Section T Errata

Rework T3.10 for clarity, by breaking off war hull text. Add B4.25 reference.
(T3.10) This is normal space that has not been surveyed by any empire. ~~It is impassable to the majority of "War Hulls" (B4.20), and the determination of whether a map hex is unsurveyed or not is made at the start of the turn.~~ Scouts and survey cruisers (B4.25) may survey it via (B4.25).

New rule (pulling in text removed from T3.10 and expanding upon it):
(T3.20) War Hulls. It is impassable to "War Hulls" (B4.20) other than SR types (B4.35). They may attempt to enter a hex that started the turn as unsurveyed, but for which the survey completed on a previous segment before the War hull attempted to enter the hex. If a War hull ever tries to move into an unsurveyed hex it immediately performs a RX-SS (C2.70) in the originating hex.
Example: A FFS completes surveying a hex on segment 4. A war hull could enter the hex on segment 5 or later. If its orders had it entering that hex on segment 4 or earlier, it would instead perform a RX-SS instead.
