Weapons gone after mission - will to play too.

I had to put my weapons into a locker to enter a certain club in a mission called Lack of empathy.
I tried to google it and apparently it's a common bug and there is no known fix. My weapons are all gone, stored in a bugged locker forever and just .. what the fuck is going on. Do I have to google every mission beforehand now to make sure I can complete it without breaking everything?
