Bugfixes & QoL changes in League of Legends patch 25.19

Bugfixes

• Fixed a bug that caused Ignite to do more damage than intended. (This was fixed in 25.18, but mistakenly left out of the patch notes.)

• Fixed an issue where one of Aurora’s joke VO lines would cut off at the end.
• Fixed an issue where sometimes jungle camps wouldn’t despawn if the parent mob was killed too far away from them, leaving an orphaned camp for eternity. Honestly we’re just disappointed that someone caused this.

• Fixed an issue where the Death Recap pings could be missing or display different spell names.

• Fixed an issue where Kai’Sa’s Shadow would linger after death until reviving.
• Fixed an issue where Blitzcrank’s R damage is not dealt around his new position after Flashing during the cast time.
• Fixed an issue where certain large pets wouldn’t follow the owning champion when coming in or out of Morderkaiser’s R.
• Fixed an issue where Ambessa’s passive could cause Ambessa’s buff bar to display some debug text.
• Fixed an issue that causes Nasus’s R to render above impassable terrain.
• Fixed an issue where Nilah’s Q and E VFX could render over structures and units.
• Fixed an issue where Xin Zhao’s feet could jitter during his Recall animation.
