What do you need help with?

i cant get it to use a negative coordinates in commands

I have the same problem, it tries to path to some unknown location. Using #goal to set goal also doesn't work I'm in negative x & z. Tried #reset, but that did nothing.

#goto -817 9 -189???

No, doesn't work. But I'm under -100k in both directions.

Edit: I did some testing on superflat singleplayer, it works near spawn, but if I tp to -100000 5 -100000 it stops working. The path line seems to go in the direction you are facing.

Tried some more, #goto -100000 5 -100000 seems to work, but using #goal or #goal -100000 5 -100000 doesn't. Also didn't work when I tpd to 100000 5 100000.
