Target always set to None

Hi,
Can you double check that the NGUI and TextMeshPro defines are set in the Scripting Build Defines?
Notice that depending on the TextMeshPro version you are using, you need to define different tags. Please check that the correct one were set by the Force Detection as described here:
( inter-illusion.com/assets/I2Localization...lizationTargets.html )

If that doesn't work, Could you let me know which TMPro component you have in that gameObject? Is it a TextMeshProUGUI or a TextMeshPro label?

Also, just to double check that the detection is working, could you add a regular UGUI text to your scene and add a localize component to it? If everything goes fine, it should auto detect "Text", otherwise there is a corruption somewhere, and it may be a good idea to delete the folder Assets\I2\Localization and then install the plugin again.

Can you please, also let me know which unity, NGUI and TextMeshPro versions you are using? I can try reproducing your issue with those conditions.

Hope that helps,
Frank
