384.5 Traffic Analysis Statistics Historical Missing

[checkyourmirrors]

I've got a RT-RC88U and since upgrading to 384.5 the web interface has been slow in responding overall. For Traffic Analysis Statistics, the historical data is missing, it only shows since the reboot and in the past, that data was still available. Additionally, it just seems off and wondering if this has been reported or any "known" issues? I am new to the software and forum and if there is a place to check for reported bugs, I am happy to go there if someone can supply the URL.
