TNT not acting correctly

Good Evening, dear Forum Members.

Me and hundreds other MineCraft server owners are having this problem with TNT.
When you try to make a TNT cannon, the TNT won't act correctly. One TNT won't push
the other TNT. The second TNT will just fall down. It's definetly not caused by a plugin I
believe because we removed all of the plugins and installed a new clean .jar. We're using
Craftbukkit 1.7.9, tried it with 1.7.10 aswell. Didn't work. We tried Spigot, it worked. But It's
important that we get it to work in 1.7.9. Has any1 ever experienced this? I know that many
people have this problem so I'll try to name the thread as appealing as possible because I've spent
hours googling this error, I found a few threads where many people have the problem but never
get an answer.

Yours,
R3voked.

 

I have experienced this and I am 100% assured that it is bukkit fault for this not working, as I too have tried using a base bukkit server with no plugins and it doesn't work. And when I switch to Spigot it does, so it's definitely a must fix for bukkit

 

Ay thats what you get for using a dev build! Have you tried the 1.7.10 beta build?

 

I have does the exsact thing aswell
