MP missing WML child crash.

[Velensk]

While playing MP today I was interrupted in the middle of my game by an Error that kicked me out of the game. It said "Missing WML child error please report." This is what I am doing.

I was playing on the 1.7.15 branch. My system is Mac OSX.

I'Ve got the same on Windows XP twice, in 1.8 version. It happens when you try to attack a unit so it's most likely the server being unable to do the random...

Same on Vista, it happend to me when the AI's attacked

What is this error? I keep getting it all the time. Im playing in 20-30 rounds and suddenly this error quits the whole game! Im about to throw my computer to the wall #@(&/)€(!
sry.............

Big thanks for reporting!
I've just fixed that particular "Mandatory WML child missing..." bug. The fix is in branches/1.8 in [rev]42123[/rev] and in trunk in [rev]42125[/rev],
and the fix will be included in 1.8.1 and 1.9.0
The usual (not only) cause was 'host sending/receiving a chat message during AI attack'

csarmi, you were correct about the fact that the bug was related to the RNG, so, thanks for this info - it helped find the bug faster.
