The mod has been re-signed. The server should be able to verify it successfully this time.

Fixed the bug:

When loading the patch "Blastcore Murr Edition (TT Version)(long smoke patch)", Arma 3 displayed the alert "Circular addon dependency detected" and shut itself down.

**Reason:**

The bug is explained on the webpage [https://feedback.bistudio.com/T180805] and summarized as follows:

1. **Problem with Dependencies:**
- Addon C depends on Addon B.
- Addon B depends on Addon A.
- If Addon A is missing, Addon B removes itself due to the missing dependency (A).
- The issue arises because Addon C, which was loaded earlier, assumes Addon B will always exist. However, by the time Addon B removes itself, Addon C has already been loaded, resulting in the problem.

2. **Why This Happens:**
- The game does not check dependencies in the correct order:
- The "skip check" is performed before other steps, so Addon C verifies its dependencies before Addon B evaluates its own status.
- This leads Addon C to believe that all its dependencies (including B) are satisfied. When B is later removed due to missing A, it leaves C in an unresolved state, disrupting the dependency chain.

3. **Misleading Error Message:**
- The error message mistakenly states it is a "dependency error."
- In reality, the issue is not a true dependency error (meaning the reported "Circular addon dependency" is incorrect). Instead, the issue arises because a required addon (A) is missing, causing problems in the dependency chain.

4. **No Support for Chains of Skippable Addons:**
- The root issue is that the system was not designed to handle scenarios involving chains of skippable addons.
- Fixing this would require significant changes to the dependency checking and loading order logic, which has been deemed unfeasible.

5. **Conclusion:**
- Developers have decided not to fix this issue and acknowledged that the current system does not support chains of skippable addons.

In my "Blastcore Murr Edition (TT Version)(long smoke patch)" mod, the `CfgPatches` class contains a subclass `TT_long_smoke_patch` that selects `Blastcore_MainCore` and `TT_Patch` as dependencies from the "Blastcore Murr Edition (TT Version)" mod. Both of these dependencies further rely on mods such as Arma 3 vanilla, RHS series, CUP series, FIR AWS (Air Weapon System), and JSRS SOUNDMOD 2025 Beta. This creates the aforementioned A-B-C dependency chain problem:

1. Here, A refers to `TT_long_smoke_patch` in the "Blastcore Murr Edition (TT Version)(long smoke patch)" mod.
2. B refers to `Blastcore_MainCore` and `TT_Patch` in the "Blastcore Murr Edition (TT Version)" mod.
3. C refers to mods like Arma 3 vanilla, RHS series, CUP series, FIR AWS (Air Weapon System), and JSRS SOUNDMOD 2025 Beta.

As a result, even if A and B are loaded, failing to load any mod in C causes Arma 3 to display the alert "Circular addon dependency detected" and shut down.
I resolved the issue by removing the dependency relationship between A and B, which successfully fixed the problem.

By the way, this issue was caused by the new attribute skipWhenMissingDependencies that was added to the CfgPatches subclasses in Arma 3 version 2.14. Therefore, this problem only occurs in versions higher than 2.14.

---

**Summary:** This is an issue with Arma 3's official system. The fundamental problem is that the Arma 3 system was not designed to handle scenarios involving chains of skippable addons. Moreover, the developers have decided not to address this issue in future versions.

This is just a signed version of v1.2 (using my private key). Since some servers enable the 'Check Signatures' option to enforce signature verification for MOD files, I have provided this version. The local version of Arma 3 does not check signatures, so if you are only using the local version, you don’t need to worry about signatures.
