@R4iscool1 Im doubtful that all the TNT exploded in the same tick.

This. It depends on how you activate them. If you have them stacked on a powered rail and and power it so they run into a block they don't all explode in the same tick. Do it with normal minecarts and you'll see they separate slightly
In this case the totem activates but you still die. You might not have seen the totem be used because you had so many minecarts. I used 5.

If you push the minecarts with a piston and drop them several blocks near you they all explode in the same tick and the totem will save you every time.

@HaloNest Where did you get that from? I'm pretty sure the colour is just dependant on how they were spawned.

I think this is bug with shulker spawn eggs where non-op survival players can change the spawner but it reverts after one tick, which is long enough for it to do one spawning cycle. Only thing I can think of that matches Dennari43 and BluePlauge's descriptions. Anyone want to make a video and a bug report?

The shells will always be purple, their colour doesn't depend on the colour of the shulkers.

I'm still confused, the shulker you placed should've been purple not white. Wondering if somehow lag meant you actually changed the spawner long enough for it to spawn a couple of shulkers before the game noticed you shouldn't be able to change spawners, or some such nonsense...

You might have actually found a bug (or an admin is trying to confuse you).
As of 1.11 shulkers summoned by commands or placed in spawners will by default be white (colour can be customised). Shulkers from spawn eggs will be purple.

Are you sure the spawner is still spawning cave spiders and doesn't spawn shulkers instead? I'm thinking it might be a graphical glitch with the spawner.

Also this means @cepheid might have the only purple shulker spawner on the server!

@TheForgotten20 @Dannysharks Thanks! I didn't realise that

Just noticed that the staff application link is for the old forums in case staff weren't aware.

Any chance of a sticky thread with these in or something similar?

@Sofatroll Not sure, if yes, see it as your pompous crypt

I'll be like Emperor Qin!

Oh crap, I logged out somewhere underneath all that. Hopefully you haven't buried me!

@FishW the death star never blew up coruscant.... it blew up alderaan...

Not to mention that that's the second death star that barely blew up anything...

@PurpleMare Ah yes, spiders are going to be a pain to use in xp farms. I tried a 2x3 sapce but you can only get up to maybe 40-45 before they start dying. I'd say just avoid using spiders for xp farms now, unless you actually want to redesign the grinder for a 4x4 area. Cave spiders should still be usable though.

The upside is if you just want the drops making a grinder is now so much easier!

One one other possibility for any mob is have several separate chambers and use the iron weighted pressure plate to count to 21 mobs (or 25 if you push some armour stands into the block).
