Cop backup never comes

[BigDeluxe 3]

Whenever I request backup in LSPDFR, it never comes or catches up to my pursuits. One time during a pursuit I noticed that I was passing stopped cop cars that had their lights and sirens going. Sure enough, I looked on the mini map and they were blipped, meaning they were a part of my pursuit and/or backup request. Why won't the cop AI move? I have no idea if it is possibly a conflict with one of the extra mods I am using, so I'll just list what I am currently using. I ve been having this problem for a few days now. EVERY extra mod as well as LSPDFR I am running IS up to date, I checked.
