User blog:Dr. Ivo Robotnik/Tekkit classic server problems

So, I'm running another tkc server, and I seem to not be able to escape painful bugs. This time, it so happens that some items kick me out of the server, or even freeze the game upon crafting or picking up, for example bows, dm pedestals, those nova bombs and so on, as well as placeable tablets. I do have ways of removing them in case it happens (until that, I had to completely remove the player file in the server), but is there any way of preventing/fixing this? Some of the bugged items would be of use.

Any help welcomed, thanks!
