Minecart with TNT DESTROYS TRACKS

Showing the tracks before the explosion, then afterwards.

I apologize if this is incomplete, but I didn't want to spend too much time with small details. I figure that the screenshots should be informative enough, if anyone wants to improve on it they can add a comment and I will add it to the issue.

These 3 screenshots (those dated 31st) are of 13w04a on Win7 latest java gamemode 0

I have tried to duplicate the described error without success. I tried N/S and E/W in case orientation was a factor and then enclosed the area to see if that had any effect see my results

confirmed in snapshot 13w05b

thanks for the confirmation, will add it to the issue once 05b gets added to the list matches

once again Kumasasa, words cannot describe my gratitude to you for your diligence

You said:

place the tracks exactly as shown in my screenshot in January, then go into survival mode and nudge the cart towards the corner, into the powered activator

This is not a controlled explosion, only if the TNT is activated from the Activator Rail is a controlled explosion which will save the tracks. Thats why it's duplicate of MC-7464.

Tails, when they fix the issue, you can feel free to mark this as resolved. but until then just let it go please.

Can you post the video for me? I can't understand how to recreate this issue.

Low quality ticket with lack of details, resolving.
