I just recently returned to Tarkov, and I'm trying to progress my quests so I need to get some gold chains to trade for a factory office key. I've gotten one so far (scav pocket), but I'm having no luck searching safes or filing cabinets which apparently were nerfed since I last played.
So- where are the best places to look now? Are there any specific spots/types of containers they are most often found in or do I just have to get lucky on scavs? Are the safes and filing cabinets still worth looting?
