I’ve reinstalled them on my primary computer (I’m so used to them it’s annoying to play without them) but the others have nothing but the game installed.
The experience is still the same regardless so I’m doubtful that addons are causing the issue, though there’s the possibility they could make it worse once it starts happening. There are also others reporting that they are encountering the problem with just the base game installed, so addons don’t appear to be the culprit.
