this is strange as I have not encountered this problem on my own game.
However, I do not think anyone should be using the beta now. It is best if everyone uses the complete v1.0 with the 1.0.1 patch, and personal experiance showed you must do a clean save for the mod to work properly, so on the readme I did update the information saying you must clean save when upgrading from B1.0 to Com V1.0.
Thanks for the update. I did use a clean saved game then this occured, so I don't now was causing it maybe the sailing mod or the old location near of Galas Malatar (KotN) has some dirty reference which still are in my game files.
Anyway, I've kept the corrupt and cleaned esp files if you wish to look at them.
The use of the clean save should be done on every step, when you switch from beta to complete version and that may also include the sail mod.
