Strangers and Freaks icons are disappearing?

[Mr Krabs]

Not a real issue to me but It's kinda annoying, the question marks are disappearing from the Map but the actual mission can still be started. Which is really annoying when I have to literally look online for the locations, and this happens every playthrough after I complete an Activity like Golf, Tennis etc. I have Simple Trainer but I don't think that would conflict.

It disappear if your character is loaded closed to it from save file or spawned within the vicinity.
Just move a distance, and it reappears.

*no clue about having cheat or trainer running.

Nope. Nothin'.

Repair ur game , some updates break the interface , no idea why but when i repaired it was fixed (i had an issue with picking up money from dead npc that the icon from +20$ didnt disappear and stayed in the center of my screen :/ untill i did that)
