So I've been messing around with Gentleman Mudkip's excellent Westeros map in Tiled, and was able to do most of what I wanted except for two major issues:

1) I can't get the Mander river system in the Reach or the White Knife river system in the North to appear on the map.  I'm thinking there might a limit on how long rivers can be, and these are very long systems.

2) Watchtower points are not spawning in the game, despite being clearly marked within the Tiled editor.  No idea why this is happening.  

Any ideas?

Apologies if this is belated, but make sure you have any errors from playtesting fixed (--enablemoddingtools on launch can help you identify some). One of the reasons I didn't include rivers is because building them in tiled is an absolute nightmare, and I had other problems as well. Good luck!
