When the timer on Lethargy stacks reaches 0, instead of decrementing the counter by one, all stacks of Lethargy on the target are removed. This works differently compared to other timered debuff effects like Beguile and Vulnerability where the counter is decremented by one, instead of all stacks being removed. Please fix Lethargy so the counter is only decremented by one at the end of the timer instead of the entire stack being removed.
