Teemo's R - Noxious Trap No Longer Procs Spell Effects [GAMEPLAY]

In previous patches, Teemo's mushrooms procced all spell effects including Liandry's Torment and Luden's Echo. After the most recent patch, however, his mushrooms did not apply the Liandry's burn, Luden's Echo, or the new keystone mastery Deathfire's Touch in the games I played as Teemo. After noticing that neither Luden's nor Liandry's animations triggered on mushroom explosions, I checked the buff bars of the enemies and noticed that the mushroom only applied the mushroom debuffs and not any item or mastery debuffs. I assume that other effects such as Rylai's Crystal Scepter or the mastery Thunderlord's Decree would not be applied as well. His Q still applies all spell effects as intended, implying that the bug is from the mushrooms themselves and is not a broader issue with Teemo.

EDIT: Tested some more and found that the mushrooms did NOT apply the slow effect of Rylai's Crystal Scepter, did NOT provide healing from spell vamp and did NOT apply the effects of Spellthief's Edge. On the other hand, Banshee's Veil still blocks the damage and slow from the mushrooms.

Step by step procedure to reproduce the bug:

1. Buy an item/take a mastery which procs on spell effects such as Liandry's Torment or Deathfire's Touch.
2. Place a Mushroom.
3. Have an enemy detonate the mushroom.

I have played 3 games as teemo so far and have not noticed any mushrooms proccing the spell effects.
