The legendary finally spawned! and I saw it the moment it did I then proceeded to throw 2 stacks of ultras and it and then watch it vanish about 2 min after seeing it. I broke all of the surrounding blocks and checked the whole island and it was no where to be found. It never tried to attack me, and it de-spawned after 2 min and wondering less then 10 blocks from where it spawned. I have never been so devastated by a game, after 2-3 weeks of waiting and watching it spawn then 2 stacks in and it got ripped away from me before 3 min passed.

Thanks for the report.

I am unable to confirm this issue -- I put up my test server and waited until a few spawned, and they were all still there 10-20 minutes later.

If you have any more information, please add it here! A list of plugins on the server may also help narrow things down further.

Closing due to age. If this is still happening, please make a new ticket!
