# Captain's Modlist v10 → v11 — Mod Change Summary

**MC 1.21.1 / NeoForge.** This is a **stability + side-correctness** pass: **5 mods removed**
entirely and **16 client-only mods re-tagged** `both` → `client` so they no longer get
installed on the dedicated server. No new content was added.

---

## ➖ Removed in v11
| Mod | Side | Why |
|-----|------|-----|
| **More Mob Variants: Renewed** (`moremobvariants`) | Both | Crashes any dedicated server (RenderLayerParent) yet registers a *required* channel, so client-only players get kicked. No fix exists for 1.21.1. |
| **Concurrent Chunk Management Engine** (`c2me`) | Both | Server-side chunk perf mod that deadlocks/freezes prod (alpha). No client value. |
| **Elytra Slot** (`elytraslot`) | Both | Soul-elytra ↔ DeeperDarker `NoSuchFieldError` server crash. This is the long-planned v11 elytra drop. |
| **Create: Structures Arise** (`create_structures_arise`) | Both | Already dropped on prod; removing aligns the pack (stops new-chunk structures). |
| **Sound Physics Remastered** (`sound-physics-remastered`) | Both | Redundant — **Sound Physics Perfected** stays and replaces it. |

## 🔧 Side-tag corrections (client-only mods removed from the server)

These 16 were mistakenly tagged `both`, so a `packwiz install -s server` was putting them on
the dedicated server. Two (`fog`, `awesome-3d-mace`) hard-crash the server; the rest were just
dead weight. All now correctly `side = 'client'`:

`fog`, `awesome-3d-mace`, `xaeros-minimap`, `xaeros-world-map`, `distanthorizons`,
`just-enough-professions-jep`, `measurements`, `pick-up-notifier`, `subtle-effects`,
`clickable-advancements`, `enchantment-descriptions`, `just-enough-archaeology`,
`justenoughbreeding`, `shulkerboxtooltip`, `smooth-chunk-save`, `tips`

---

**Server-admin takeaway:** when updating the server jar, **remove** the 5 mods above and **skip**
all 16 re-tagged client-only mods (they should never be on the server). After this, prod no
longer needs its manual server exclusions for c2me / elytraslot / create_structures_arise —
they're gone from the pack. Sound Physics **Perfected** remains.

## 🔁 Also in v11 (later edits, same version)

**Mod update:**
- **Create Aeronautics: Copycat Wing** → **1.0.2** (CF file 8215540). Bugfix: 1.0.1 hard-crashed
  the server (`copycat_slice` had no `facing` property → `IllegalArgumentException`); 1.0.2 guards
  the `getValue(FACING)` calls. Pure bugfix — no client lockstep needed.

**Mods added:** `drive-by-wire-sable`, `drive-by-wiretypewriter`, `durability-tooltip`,
`every-compat`, `mining_and_placing_animations`, `snow-imprints`, `starbunclemania`.

**Mod removed:** `rightclickharvest`.

**Side fixes for the new/edited mods:** `xaeros-world-map` re-set to `client` (a Prism re-download
had blanked it); `starbunclemania` set to `both`.
