combat.lua:320: attempt to index field 'addon' (a nil value)

I get this error upon entry. There are no other addons enabled when this happens:

45x RotationMaster\Conditions/combat.lua:320: attempt to index field 'addon' (a nil value)
[string "@RotationMaster\Conditions/combat.lua"]:320: in function evaluate' [string "@RotationMaster\Options/conditional.lua"]:69: in function <RotationMaster\Options/conditional.lua:56> [string "@RotationMaster\Options/conditional.lua"]:34: in function <RotationMaster\Options/conditional.lua:26> [string "=(tail call)"]: ?

[string "@datastore\libs\AceTimer-3.0\AceTimer-3.0-17.lua"]:55: in function <DataStore\libs\AceTimer-3.0\AceTimer-3.0.lua:50>

I've been forced to use the previous version because this pops up a lot.
