I’ve tried playing on several worlds on v1.21.5 and every one of them have had the same outcome after about 30 minutes of playing. With or without cheats or experiments, in survival or creative, modded or not, the interact box disappears and makes me unable to place or break blocks, but I can still hit mobs.
It doesn’t fix itself after closing the world, game, or launcher. I’ve tried adjusting settings, thinking I might’ve toggled something and just forgot. Nothing has brought it back and I’ve lost several worlds.
The issue hasn’t happened on older versions, like the April 1st update or before. I’ve been playing on 20w14infinite and 25w14craftmine recently and haven’t had the issue.
My computer sucks so I can’t attach any sort of recording to show it happening.
Unable to reproduce. Perhaps it is the fault of the mouse you are using. If not please share more info.
