Unable to return a caravan back to the original base if it is an adjacent tile.

[jacko21297]

After sending a caravan 1 tile away following a north east direction, the user was unable to instruct the caravan to return to the main base by following a south west exit direction. The option to send the caravan South West is not present.

STEPS TO REPRODUCE:
1. Load RimWorld Dev BuildID: 1522239.
2. Create a new game.
3. Create a caravan from the world map, instruct the caravan to head North East.
4. Once the caravan has reached the adjacent tile, attempt to send the caravan South West.

ACTUAL RESULT:
The 'Exit Direction' menu does not allow the user to head in the direction of an already occupied adjacent base.

EXPECTED RESULT:
The user should be able to send caravans to pre-occupied adjacent tiles.

ADDITIONAL INFORMATION:
Please see the attached screenshot for further reference.

I believe if you send them to a tile adjacent both the starting and target locations, you'll be able to enter the destination instantaneously, by going to world map and ordering them to enter the destination.

Also works for Attack if the destination is foreign owned.

Trading requires that they actually navigate to the center of of the destination tile via world map travel (non-instant), which is presumably analogous to them walking around the foreign camp. Probably for the best.

So the bug is: if the player has 2 adjacent bases, then he can't send caravans directly from the first one to the second one. I think it's just a little quirk. It shouldn't affect gameplay that much because you can always send a caravan to any other adjacent tile and then just instantly enter the base. I'll leave this for Tynan to decide.

I'm not gonna call this a bug, though maybe we should disallow adjacent bases.
