Trigger rollup summary field not working on merge

Hi All,

I am trying to roll up the count of a custom object on the parent account. The custom object is related to Account via lookup relation. It's working fine on the update, insert and delete but not working on Account merge. As per Salesforce guide child object triggers are not fired on Merge. Did anyone have a similar issue like this? If yes, please suggest if there is any workaround. Thank you!
