[PSP] Paranormal Investigator: Didn't receive extra pay amount

My sim has maxed out the Paranormal Investigator carreer, and received a raise a few times. Currently, he should be getting paid 3,400 simoleons, for the expert category, instead of the inicial 3000 pay. But when he comes from the job, he always receives only 3000, either I go with my sim to work or send him alone, I never get the extra money. 

On the panel to select a gig, it also only shows the original base price, but on the carreer panel it shows the correct amount my sim is suppose to receive.

Edit By Crinrict: Adjusted Title fit migrated bug report. Archived thread had around 6 me toos. Also added missing thread tags from info of the old thread.
