TNT Will Not Interact With Players?

Hey guys! Last night I watched a tutorial on how to make a human launcher using TNT Minecarts, and I said to myself "That would be so cool to have on my server!" So I set it up, but when I go to launch myself, I don't move at all. I stacked 100 TNT carts on top of each other inside a bedrock barrel, stood on top of them, and set them off. Just to be sure I wasn't doing anything wrong, I went over to singleplayer vanilla, and it worked fine (Got to about y=2200 or so). After this, I moved my plugins folder out of the server file, and restarted the server. Still it didn't work. So after all that I'm pretty sure it's something with Bukkit or just the way that Minecraft servers work, and I was wondering if anyone had any ideas on how to get it to work?

EDIT: Actually TNT doesn't seem to interact with other tnt either, although I just noticed this when I reloaded all the plugins.

Just in case they did interfere in some way (even when I moved them out of the folder), here's the plugins I have:
Essentials (Chat and Spawn as well)
CoreProtect
Lockette
WorldEdit
PermissionsBukkit


Server Stats:
Version: 1.7.10
Build: #1950
RAM: 1500 MB
OS: Ubuntu 14.04

Any help would be greatly appreciated!

-Cheers!

 

Do you have it turned off in Essentials?

 

No, essentials is set to not interfere with explosions (All Items in the Config on the topic are set to false)

 

I've been away for a couple weeks, but I'm going to revive this as I still haven't figured out how to fix it.

It's a bug in the Cratbukkit builds.
