Whenever I wipe the server the seed stays the same, even though I leave the server seed blank. I am using a wisp panel btw.

Which map are you using?

I am not using any specific map. I want it to be random every time I wipe.

you need to create a random number in your bash/bat script and use that, the default seed is 1337 and it will use that if you don't supply one

Is there any way to do that automatically though? I tried to do a random number generator command that would give a random number between 1 and 2147483647 every time the startup script was executed, but it switches maps every time a new seed is put in so that didn't work. 
kaysharp has a plugin that could do something like that but better automatically, but it would remove some features with the panel I am using. Not sure how to solve this tbh, maybe I'm just stupid. And before you say anything, I am not really interested in doing it manually. I know there is a solution to this.
