[WFRP4e System] Player applying damage throws an error

[moo-man]

When a player attempts to apply damage to their actor (from an opposed test), the damage applies, but the damage card does not update to show the damage taken. This error appears in the console.

Uncaught ReferenceError: msgId is not defined at OpposedWFRP.updateOpposedMessage (wfrp4e.js:3609:84) at Object.callback (wfrp4e.js:19604:25) at #onClickItem (foundry.js:55518:11) at HTMLElement.dispatch (jquery.min.js:2:43064) at y.handle (jquery.min.js:2:41048)

This only happens to players, not GMs.

To reproduce: Be a player. Lose an opposed test where they would take damage. Attempt to apply damage.
