Supply across strait

[Courtenay]

In this picture, Wavell is out of supply, and I can't figure out why. As far as I can see, he should be able to trace three hexes to Bahrain, and from there via CPs back to India. I searched for the string "strait" in the manual and looked at the Terrain Effects Chart, and while moving across a strait costs an extra movement point, I can't find any indication that supply paths across a strait cost more than one point. Also, if MWiF is tracing the supply route from Bahrain to Wavell, that would cost four hexes because of the desert hex that Wavell is in, but that is not the direction that supply paths are traced. One traces "a supply path back to a primary supply source." The strait does exist; Wavell just crossed it.

Am I making a mistake of some sort, or is this a new supply bug?

IMO bug, unless there is something we are not seeing.

HQ should be able to trace to India, I cannot see (at least in RAW and I dont think it will have changed in RAC) any reason why strait hexside should add cost, so it should reach. Weather is fine...

Looks to me that Bahrain is a desert hex so the path would be at 4 already before tracing to India.

[Centuur]

No bug. Bahrain is indeed a desert hex.

[Joseignacio]

Bahhrain is desert? Then yes.

[Courtenay]

Wow. Thank you. You are right, the game indicates that Bahrain is a desert hex. I would never have guessed that. It doesn't look like a desert hex. My apologies for wasting people's time.

Fortunately, by moving Wavell two hexes to the northwest, he can trace supply to Kuwait, and the invasion of Saudi Arabia works.
