From e13091514616dcf6c0057f52ae7ab4249cac338f Mon Sep 17 00:00:00 2001 From: adu-crypto <94821467+adu-crypto@users.noreply.github.com> Date: Wed, 17 Aug 2022 20:56:02 +0800 Subject: [PATCH] fix: the occasional staking module `SimulateMsgCancelUnbondingDelegate` failure (#12933) ## Description --- This is a temporary fix targeted at staking module simulation for #12931. We should randomly choose the unbonding entry `CreationHeight`, and then fetch the first entry that matches the `CreationHeight` to make sure we can get the correct entry balance. ### Author Checklist *All items are required.
