INFO 2021-03-19 15:49:42,784 main WARN Disabling terminal, you're running in an unsupported environment.

Me and my friend are making a modded 1.12.2 server (We are only using tinker's mod pack).  We both loaded into Minecraft died twice by mobs and I broke a tree then the server crashed. I was confused so we tried to log back in It said disconnected. We then restarted the server with Multicraft then tried again changing nothing  and it said (internal exception: java.io.IOException) I figures something was going on. But at the same time my friend  was able to login no problem and play until I tried to log on. Me logging in crashed the server evrytime. After a couple attempts the same error came up for my friend. I then went to shockbytes multicraft console fo rthe server and noticed three Warnings from the moment of me joining to the server stopping. All of these had relation with position in the world.

There where also a Error about location also 

Chunk I/O Executor Thread-8/ERROR [FML]: World: (144,64,-160), Chunk: (at 0,4,0 in 9,-10; contains blocks 144,0,-160 to 159,255,-145), Region: (0,-1; contains chunks 0,-32 to 31,-1, blocks 0,0,-512 to 511,255,-1)
 

It prints the Warning's and Errors on  screen with many other lines of code saying the coordinates of the player and other nonsense (that I will include after this parargraph) Several time I counted on time 9 times.
