I don't have discord.There is smart and manual cursor modes in all console terraria versions.
I aint sure, if it does have press X by default to use (or possibly Y). If you want to be sure then look for Lock On in keybinds
You must have placed a target dummy or item frame, which must cause this. Since you dont often really use target dummys or item frames in a normal glitchlesd play, the developers probably missed that bug.
Use the #looking-to-play channel in the official discord to find someone to play with.
