Posting my problem here again, this is unsolved for a few months now D: -
Ender's client interface just freezes/stops working from time to time. This is not lag or complete client freeze, just the interface - this means I can still move around in the world but when I right click anything the menu doesn't show, my chat stops working, I cannot open inventory, char interface, etc. If I restart the client it starts working again.
The error is really gamebreaking for me because this can happen when I'm fighting an animal/someone... which means I have to restart the client while I'm in the fight.
Any help on this matter will be greatly appreciated.
