Hello, I'm writing this on behalf of my good friend who isn't tech savvy. We run a private server (from a server provider) with a couple of mods (Compo pack and three others) and sometimes when she opens a loot window, her game will freeze for a couple of seconds or crash. I'm not the most tech savvy person, but I suspect it's a memory issue. Her PC has 8GB of memory, which is the minimum requirements. The game runs smoothly most of the time. We have monitored her memory percentage through the task manager, and it steadily increases over time getting very close to hitting the maximum. Is this a known issue and does anyone happen to have any ideas? Much appreciated.
