As stated below the grab command has been directly related to the last few freezes, the issue is 2 fold.. player scripts and the command has some poor code in it. I am moving it over to function exactly like the claim command does while I work out how I want to resolve this. I am fairly certain the person who designed grabbed never seen it run with multiple players using the [grab command over 20 times a second each. (I am not overstating the numbers either, the command log proves what is happening at the point of the freeze). So for the moment you will have to deal with the command change while I figure out a solution that does not freeze the server, please fix your scripts as well.
Version 78
