This is only happening on loading balanced MVC app. If I am only running one instance it's working fine. Since the bundle is generated on the fly when opens index page, this is what happened (my theory):
Can ABP add an attribute such as preGenerating=true into <abp-style-bundle>,<abp-style>, <abp-script>, <abp-script-bundle> tags?
