I'm not really sure when it started or if it was from the very beginning but I know that I had this problem for a long time now.
Whenever I start BG3 the game takes several minutes to connect to mod.io and load my subscribed mod list. It also always takes a good moment to load either the browse or installed section of mods. I have over 5GB of mods downloaded right now but I think this was also an issue very early on before I had so much downloaded.
When I open mod.io on my browser it pretty much always loads quickly. Would this be some weird connection issue or does it have something to do with the game?
