How to reproduce

Just type #follow player (player name which in my case was filtys00)

Final checklist

• I have included the version of Minecraft I'm running, baritone's version and forge mods (if used).
• I have included logs, exceptions and / or steps to reproduce the issue.
• I have not used any OwO's or UwU's in this issue.

Reproduced with
Minecraft version: 1.12.2
Java version: 1.8
Baritone version: 1.2.14
It only happened when I tried to follow a player that was either not online or out of render distance

It only happened when I tried to follow a player that was either not online or out of render distance

That's not a bug tho

Should I open a new issue for that?

I guess it should not tell you to report the error here if it's not a bug

Probably

It seems that I also encountered this problem.

Minecraft version 1.15.2;
Java version: 1.8
