btw everytime someone joins, leaves or dies my server gets a lag spike
timings

I am currently looking into this but it may take me a day or two, about a month ago my raid array for my hard drives failed ( containing the ItemJoin code ) and I have sense ordered new parts and they will be here tomorrow and I will be able to rebuild my array and access the ItemJoin code.

I will post back here in about a day when I have further updates to this bug.

This is because you were in creative mode, the even that triggers the hit player variable did not detect any damage attempting to be made to the player so it stayed the default one.

I have sense changed this to player interact event so it will now always work. This fix will be uploaded with v3.7.

I will post back when v3.7 is released.

ItemJoin v3.7 has been released and you can get it here;
