Seems like every time I load in, there's a decent chance I'll be booted out with a guitar error within a minute. If not, there's a decent chance it'll happen at some point near the Level 3 encounters. I've cleared my Steam cache multiple times now, and nothing seems to work. I've been trying to farm a specific roll of Ergo Sum, but in these conditions, it's so unlikely that I'm able to even finish the event, and it's become extremely frustrating.
