Done Bug Report - Unsure

[iforgetwhyimhere :D]

What type of bug are you reporting? Unsure

What is the bug?
When using Abilities that cause stat stage changes, error logs appear in the battle chat:
Example:
> TypeError: Cannot read properties of null (reading 'rememberAbility')
> at Battle.runMinor (https://play.pokemonshowdown.com/js/battle.js?0.09756734343997464:2404:11)

This does not stop the stats form increasing/decreasing, but does prevent the name of the ability from appearing.
Example: Landorus with Intimidate switching in:

UTEC2024 sent out Landorus (Landorus-Therian)!
TypeError: Cannot read properties of null (reading 'rememberAbility')
at Battle.runMinor (https://play.pokemonshowdown.com/js/battle.js?0.09756734343997464:2404:11)
Alakazam's Attack fell!
