[1.4.2] Leveling up with a sustain active can break the game

[Doctornull]

The Null New Gems addon has a race which uses a sustain to move.

The sustain sets two temporary values, "never_move" and "knockback_immune".

From the log, I wonder if the game engine is trying to deactivate the talent twice?

Code: Select all

Anyway, what's going wrong here?

Is there something new about sustained talents that I need to update in Null New Gems?
