Quick answer: When selling an item that is currently equipped, unequip it (which recomputes stats) before removing it from inventory, or block selling equipped gear entirely.

If a player sells their sword and keeps the attack bonus, the sell never unequipped it. Here is how to keep stats consistent through a sale.

How to fix it

1. Unequip before removing

In the sell handler, if the item is equipped on any character, unequip it first so the stat recompute removes its bonus, then delete it from inventory.

2. Or forbid selling equipped gear

Alternatively, grey out equipped items in the sell list so the player must unequip them deliberately before selling.

3. Recompute derived stats

After unequipping, run the shared stat-rebuild so attack, defense, and resource caps reflect the removed item immediately.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every Unity error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

The bug you can't reproduce isn't gone — it's just invisible until you capture it from the player's device.
