Trying to use /rtp returns the following error

"Could not execute command '/rtp' Reason: Spawn not set (RTP chooses a random location a preset distance from spawn.)"

I've set the spawn with '/setworldspawn', but still get the spawn not set error...

Edit: Using 0.24.5-mc1.18.2, with All of Fabric 5 - 1.3.1 MCv1.18.2

You'll need to set the Essential Commands spawn point with /spawn set
