My situation is very similar to yours. I originally submitted my application in Oct 2017. OWP application was returned due to insufficient fee in Dec 2017. By that time, I was already out of status (my old status expired in end of Oct). I resent my full application to Vegreville in December. In Feburary, I was able to link my CIC account to OWP application. Two weeks ago, my OWP was approved. I got them in mail in the following week.
Since you're able to link to your account, that means your application got accepted. just give them some time. You are still in status now, so don't worry too much
