Tekkit NullPointerException

[7h3JP]

Hello

I setted up a local Tekkitserver (for me and some friends) and used the Launcher to download the modded client this Thursday. Firstly I would thank all of the tekkit team and the mod develpers for your great work.

Unfortunately my client throws some times a java.lang.NullPointerException. I couldn't fully reconstruct the situation but it seems that it happens, when i break a Stone Transportation Pipe and walking onto the position where the pipe was. (But it happens not everytime, so I can't post a picture where it surly happens.) When I then try to login (after Exception) to the same server it throws another NullPointerException bevor the loadingscreen finished.

My workaround atm is to remove the players .dat file (./world/players/playername.dat). After that I can normaly login again (but loose all the items and start from new position).

I hope you can fix this

Greats 7h3JP
