dear Community,
my mining laser will fire only straight up oder straight down depending on my target angle, the shot is flying where it should but its not breaking blocks or have any of the effects it should have, instead its like a invisible shot is fired right below me. so when im falling and i shoot i hit myself. The game is not crashing and it continues as it should do ive testet it in every mode on a few of the commonest blocks (dirt, stone, sand, etc...). The strange thing is that all was fine with the 
as i started the server, but after ~3days this bug occured and i dont know how i can fix this, when im starting a backup the bug is gone, and when i erase the map and create a new one via "launch.exe" the bug is also gone, so i guess it has to do something with the map file. Unfortunately i got no experience with Java or the coding of IC2 so i hope you can help me 
(If it is helpful: a recipe from Redpower2 has also Deactivated itself, i can put things together right and it wont get me the crafted item, like the bug with the laser this occured also after a time with no special event that i could suspect to be the reason....)
Im running Tekkit 2.1.1, Win7 64bit Java
