Thx for the report. I am no expert in this equivalence t-Test. But are you talking about Cohens d being -0.497? And you think +0.497 is correct?
And then you want it to be between the CI which goes from -0.181 to 0.05? That certainly does not make sense. Changing the sign of -0.5 to 0.5 does not make it fit into the CI.

So yeah, I am at a loss here.
@Jillderon or @vandenman any idea?
