Thank you so much for this review and suggestions! It helps a lot! :D
The most frustrating thing to me too is the lockers disappearing, I have had this bug for a few builds now, but it never happens to me when I'm working on the game, it only happens in the released game, so I have no idea what's causing it.
It's the locker 27 from the army, and the 4th locker from the brothel, There is nothing in the game that should make them disappear, but somehow they still do! T-T
Just yesterday I did fixed the Helmets from the army mission from disappearing, but why the lockers too? @_@
I will keep trying to fix this and the other bugs for the next build.
