The mod Caspers Speed Toggle (1.1.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event CaspersPlayerSpeedMod::cycle-player-speed (ID 202)
CaspersPlayerSpeedMod/control.lua:21: attempt to perform arithmetic on field '?' (a nil value)
stack traceback:
CaspersPlayerSpeedMod/control.lua:21: in function <CaspersPlayerSpeedMod/control.lua:17>

Disabling and re-enabling the mod fixes the issue but can't be doing that every time I load the game.

thanks i will look into it for you :)

just uploaded a test to try and stop the bug, is this single player or multi? let me know how it gos

Seems to be fixed now, thanks.
