What were you expecting to happen, and what actually happened
Applying any of the many infinite turn status effects followed by the same status effect with a turn limit will cause the amount of turns of the status effect to be -1 the intended amount. This also occurs when done in the inverse order. This in most situations isn’t that big a deal, but is most detrimental to the Shaman class that has an ability that is dependent on how many turn stacks of poison and venom are on the enemy
How often does this happen? When did it begin happening?
100% of the time since the start of early access.
Steps to make it happen again
1: Apply any infinite turn status effects, like Channel Poison.
2: Apply a turned based instance of that same effect, such as Poison Spray.
3: The poison effect should now be 1 less than the withering effect due to the infinite poison stack reducing 1 turn of poison from the turned based poison effect.
