Is there anyone else after patch 7 who can't open chests, barrels and other items to open? I approach, click on them, but there is no reaction...
If the issue persists ... I had the same problem. I couldn't open containres of any kind neither by left clicking nor by using the context menu that was not opening. Simultaneously I wasn't able of lockpicking because the context menu did not open. All other team mebers were not affected.
I had only one mod running (Valdacil's Half-Illithid Effect Toggle) which made no troubles playing other characters, but whoever whispered that in my ear, I once deactiveted the mod (via In-Game Mod Manager), loaded the game (despite of the warning ... by deactivating the game could run unstable ...), the saved the game and activated the mod again (via In-Game Mod Manager) and all was fine. Let's see how long it will remain like this. ;-)
