When I set durabilitymultiplier to 0, my equipment and tools still degrade on use, this is the same for everyone who uses my private server. Before the update, what I would do to was set the durabilitymultiplier to -1.0. This would instead add durability, thus items would not degrade. Now however, I can no longer change the setting to -1.0 and cannot obtain infinite durability on my tools.
Ditto. Still doesn’t work in SP as well.
