Water dragon went to fight a 10 camp successfully and died. Why?

[fantasy11]

Sent a waterdragon with 100 k longbowmen and it was a victory. Waterdragon died. Why? Now I got to wait until tomorrow for it's recovery, again. Happened yesterday too.

[Sereture]

I sent my water dragon with 89999 longbowmen to a lvl. 10 camp. I have done so successfully countless times, but this time, all the men (including the dragon) died.
Why did this happen?

If this is a bug, I'd like my men and 500000 power back, thank you very much.

Edit: I seem to be unable to get into the support section. That's why I'm writing here...

If you read the wiki, you will see a clear warning on using LBM on camps higher than level 5. Using LBM can at any time, trigger the RNG to kick in causing a partial to total loss. It can happen at any time. Even after several successful attacks. The best thing to use for higher level camps is LJ. This is not a glitch or an error. It is a valid battle, kabam makes the battles differ to try to simulate real life battles.

RNG will bite you if you use lbm on a lvl 10 camp. I prefer lava jaws

The RNG is always dangerous with LBM. If you're taking the risk of using LBM on level 5+ camps, at least send AT, so they take the damage instead of your LBM. If you send 10k-15k AT, you could lose 3k-4k of them, but at least save your LBM. As the enemy focuses on your AT, the LBM get enought time to kill everything. If you have higher levels of medicine, you can save even more AT from death.

With all that said, if you don't have Lavas, better use BD, as they are the next easier to get troop after LBM (and they don't get affected by the RNG)

Guess it's just no fun being a non-ruby player...
