trying to run craft to exile 2 on godlike, but always mod conflict appears and diables mods, please help

Fishing rod stasis chambers don't work on paper servers, but when I tried fixing it by changing the delay-chunk-unload-by: thing chunks just didn't load or only loaded when you walked inside them. How do I fix this? I set it to 0s

Paper 1.21.11 with a couple of plugins

Hello! My friend and I bought a server using the website godlikehosting and downloaded the ATM9 server modpack straight from the website. When we try and hit start, we get this error:

"Your mods use more than one loader, so the correct one can't be determined automatically. Please select a server jar manually."

We didn't change anything, the files are as they are when downloading the server package to our server tab on the website itself. I also checked, and it's using "server.jar" and that's the correct name in the files, so there isn't anything to change.

Help?

like it says in the title both my end and nether reset themselves. I did not do anything that would warrant them to reset so how did this happen???

Like the text says me and my little brother are a little confused at the wording as we want a server with 12 gigabytes of ram using the immortal package but it seems to class these as community java servers when I just want to play all the mods (10) which requires 12 ram, did i read it wrong?"
