I just clicked on research scouts on my smithy which costs few hundreds of each resources. After clicking on Research Button research started but quanitity in my top bar indicating my warehouse status didn't reduced resource status. It got updated only after I clicked on my main village link i.e. by user action which reloads the page.
Steps to reproduce:
Click on any research option at smithy
