[deathbyc4]

are you using managers by chance?

 

[Slapyurmomma]

yes there was managers in the area, i just reset the area that the problem was at and that fixed the problem.

 

[deathbyc4]

may want to send that error to eloraam just in case

yes there was managers in the area, i just reset the area that the problem was at and that fixed the problem.

I just got this on my server too. What does "reset the area" mean? Chuck reset? How did you do that?

 

[Fantasix]

This is not "Solved", problem's still here !

Here's how to reproduce (It will corrupt you save file forever) :

You'll need :
- 1 Manager
- 1 Chest
- 1 Pneumatic Tube
- Something to power the manager
- A random item

Put the random item in the chest. It will be sucked in by the Manager. The Manager's light will then turn to red.

Then, just put the same random item into the Manager's GUI, and the game will crash.

Fanta'

very late and i am very tired now...managed to get in with mcedit and delete the affected blocks..well and a few others...world is saved..

My problem seemed to be when an item from the tubes went into the manager. Because the tube was not moving that many items I had just enough time to log in and break the manager that was causing the problem. I was the one that placed it so it crashed where I was standing. I guess I was lucky to have enough time to remove it.
