Some weird behaviour between constant redeclaration and file naming?

General

Facing some weird issue where the constant folding is triggering weirdly, as if file naming is affecting whether the program will be compiled or not.

Here’s the dir structure I had:

project/
├── Entry
│   └── Flags.odin
├── Import
│   ├── ... /* more files */
│   ├── EngineBaseTypes.odin <--- I want to rename this file to ImportedBaseTypes.odin
│   └── Format.odin
└── main.odin

There’s some flags declared in Flags.odin:

package Entry

@(private = "file")
BUILT_VIA_ENGINE :: #config(BUILT_VIA_ENGINE, false)

/* ... */

INTEGRATED_TO_ENGINE :: BUILT_VIA_ENGINE

EngineBaseTypes.odin (which I want to rename to ImportedBaseTypes.odin), contains some redeclarations:

package Import

import "../Entry"

INTEGRATED_TO_ENGINE :: Entry.INTEGRATED_TO_ENGINE

Format.odin uses this redeclared flag.

package Import

when INTEGRATED_TO_ENGINE {
    MyStruct :: union {
        i32,
        f32,
    }
} else {
    MyStruct :: union {
        i32,
        b32,
    }
}

Here’s the problem: when I perform the rename to ImportedBaseTypes.odin, my program doesn’t compile anymore.
In Format.odin, it says INTEGRATED_TO_ENGINE is not a constant, and in ImportedBaseTypes.odin, it says Entry is an unknown identifier, even though there are other usages in the file, which compile just fine.

This is not the first time it has happened to me and I feel it is directly related to the alphabetical sorting, but seems like a bug.

Just checked in an external project, even this minimal example with showcase the behaviour.

Output:

.../project/Import/Format.odin(3:6) Error: Non-constant condition in 'when' statement
        when INTEGRATED_TO_ENGINE {
             ^~~~~~~~~~~~~~~~~~~^

.../project/Import/ImportBaseTypes.odin(5:25) Error: Undeclared name: Entry
        INTEGRATED_TO_ENGINE :: Entry.INTEGRATED_TO_ENGINE
                                ^~~~^
