will cause online games to go Out of Sync if these files have not been updated with the new water and forest types.

Another sign of incompatibility include the Tundra random map appearing as a sandy map instead of snow .

I noticed that a few of us here use these files to design maps, so if you do get OOS' (out of sync), this is without a doubt the cause.

How to fix the error:

1) Add the new AoM Titan water types to the Waterbodies.xml
2) Add the new forest types to the forest.xml

I hope this help those with these problems. If there is anything unclear about what I said, or if you have a question, please let me know =).
