I've found a bug that crashes my client every time i try it no matter what i try.
when i use the eye to inspect an item that is enchanted, or has a rune on it it will display the usual text describing the item, and showing what the runes or enchantments do, but if i right click one of the lines of rune or enchantment description text, the client closes immediately every time. it gives me a crash report screen right afterwards.
at first i was trying to copy text to show what the runes on my new chisel did, but that was not working. then i tried to copy the text on my shovel enchantment, and then on a trowel. each time i attempted to copy the text, the client closed the minute i right click.
