I'll cut to the chase and give you an example on how they're broken.
Turn 1:
I use Spikes

Turn 2:
Opponent switches out
The game states the opponent is affected by the Spikes, however the opponent did not take damage
Examples:
https://media.discordapp.net/attachment ... height=701
https://media.discordapp.net/attachment ... height=701

Turn 3:
The Opponent switches out again
The Opponent is finally affected by the hazards

TLDR; Hazard moves take an extra turn to take effect
This is the case both if the NPC uses these moves, and if the Player uses these moves.

Sorry, I realized a little late this was in the wrong thread, I posted a ticket in the right one
