IllegalAccessError, cannot acces class

Please, I am using AIDE IDE on android with libgdx and everything was okay until I got error message:

I've tried making uuid field public before, it didn't work. Also removed getter, still didn't work. Can still access toString() of Creature from DungeonRollcall. Why? Please how do I fix?

The posted code looks like it should work. Are there other versions of the Creature class where myid() was not public?

Does the Creature class need to be instantiated through a derived class?

No, the previous version had a public uuid and no myid, so I thought myid getter might work, the version before that had no uuid. And creature is not gotten through derivative and is not used as one. I tried this on another device that had not used java before, where no dex or class or system files could be loaded, still got error.

It cannot access other things like currentAction, but can access stuff all classes have like toString.
And I find it strange it says virtual method? Doesn't that mean that the instance is null?(Couldn't edit)

Did you do a clean and a full rebuild?

Try making the Creature class public.
