It is now possible for Speeder to reset line 85 attack speeds and line 86 max timers when Speeder is disabled or closed. However, because addresses change whenever you zone, it is only possible for Speeder to reset the speeds if the animation occurs at least once after zoning. In most situations, this should allow you to disable the hack mid-fight without issue.
The line 85 speed hack should now work properly on the Taiwan client.
These changes require Speeder version 151+.
