Using the WeakAura version 2.17.12-7-ga3a028b5 and Stop Motion version 0.9.5 I am no longer getting any options for Stop Motion weakauras. The right hand panel (Where display, trigger, conditions, etc.. tabs usually are) is completely blank. I also receive the following error message:

1x ...Ons\WeakAurasStopMotion\RegionOptions\stopmotion.lua:287: attempt to call field 'PositionOptions' (a nil value)
[string "@WeakAurasStopMotion\RegionOptions\stopmotion.lua"]:287: in function create' [string "@WeakAurasOptions\DisplayOptions.lua"]:94: in function ?'

[string "@WeakAurasOptions\AceGUI-Widgets\AceGUIWidget-WeakAurasDisplayButton.lua"]:579: in function <...eGUI-Widgets\AceGUIWidget-WeakAurasDisplayButton.lua:539>

I was able to fix the errant code.

Changing line 287 in RegionOptions\stopmotion.lua from
position = WeakAuras.PositionOptions(id, data, 2),
to
position = WeakAuras.commonOptions.PositionOptions(id, data, 2),
corrects the issue.

That should be fixed now.
