I removed multiverse and it seems it work, after tons of testing i think i've figured out the problem. When I load in too many worlds the server throws up the annotated error. it's definitely interesting as i don't know how to delete worlds without multiverse.
 
Edit one - Yup, the problem occured when I load in too many worlds, i think about three. It's probably because i'm losing space to minehut not deleting plugin configs when you remove plugins. I deleted all my warps from file manager and server starts up again. I'll try removing unneeded plugin and config files and will edit again, thanks for all the help 🙂

Edit two - Turns out minehut has inbuilt deleting, command is /delete

Edit 2.9 - Trying to install multiverse, mv inventories and mv portals again, lets see if it works.

Edit 2.91 - LETS (Can i swear here?) F**CKING GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO, Multiverse loaded without any errors, time to try setting up my spawn worlds and stuff. Thanks for the help everyone.

Edit 2.92 - After I loaded in two worlds and tried setting things up, server stopped responding to ingame commands, which is a sign that's its about to die lol oof. Might not work, but i'm still happy that it loaded in Multiverse without issues. The error is back, time to debug.

Edit 3 - Tried reseting multiverse's config, didn't work. Had to remove it, i'll try downloading a RAM Optimisation plugin or something of that kind.

Ending - At this point, it seems unreasonable to try working on the server. I'm going to reset it because managing worlds is very important and i think I can implement new things to the server now, Thank you all for helping 🙂
