Oh, I assume you're talking about Haru's "Blur" ability. The wording was correct, it was indeed a trigger issue. The Removal Conditions for the Dodge Rate state didn't have "Remove at Battle End" ticked. Whoops!
(Haru was generally a lot less popular than Shiro as a party member, so I guess we're only coming across some of these things now)
That one needed no investigating, thankfully; I've already patched it and uploaded a fix! Thank you once again for pointing out these bugs!
