Bossbar is not always visible [1.8]

[WoutDev]

Hello,

I am using BarAPI v3.3 (Build #33) and using the API for my plugin. I am using spigot 1.8 (http://gyazo.com/daec16b102f0b471d32463498e5cff22) but the bossbar doesn't always show up.

Some players have the bar only if they are watching the sky (watching up), some only if they watch the block under them. Some even doesn't see the bossbar at all.

The're no errors, no warnings. It is just that the bossbar doesn't show up to players, or flickers somethimes if they move around.

I hope this bug can get fixed, because it is pretty annoying to the players.

Wout
