Steps to reproduce

package A

• source at left, test case at right (which runs fine)

package B

package nested2

import (
	"std"
	"gno.land/p/demo/nested1" // panic
)

Expected behaviour

should return g17rgsdnfxzza0sdfsdma37sdwxagsz378833ca4, I think

Actual behaviour

panic

When I reproduced and executed the steps describe as is, the value stored in the variable opa (declared in nested1 package) is now correctly output from the file in the nested2 directory.

It seems that it has been fixed by another PR now, but I'm not sure which PR it is. the directory structure I tested as follows:

.
└── examples/
    └── gno.land/
        ├── nested1/
        │   ├── foo.gno
        │   ├── foo_test.gno
        │   └── gno.mod
        └── nested2/
            ├── bar.gno
            ├── bar_test.gno
            └── gno.mod

Test Result

=== RUN   TestShouldReturnOPA
opa: g1uyjq8mwwn4rw6g42tnhjryawma7q8x7sqjcef2
--- PASS: TestShouldReturnOPA (0.00s)
ok      examples/gno.land/p/demo/nested2

Possibly related and fixed by #2856. Feel free to re-open if you can replicate; but we need better replication steps. (What commands did you run? Can you make a txtar?)
