Put the summary of the bug you're having here

What I expected to happen was...:
Type /kill to get out of a mod view in spectator mode

i was back in regular spectator mode but i still had the creeper shader. i tried different gamemodes and maps and still had the shader effect. the effect went away after a game restart. Reentering the creeper and going to another gamemode will fix. This bug goes with all mobs with shader effects in spectator mode. entering another mod like a sheep without a special shader will also fix this bug.
Steps to Reproduce:
1. Enter creeper in spectator mode
2. Type the /kill command
3.Effect will still be there even after a gamemode or map switch.
