Once Detached—Unable to Create Styles
# Summary
I believe once you detach a text style from a layer, the plugin is unable to create new text styles for the _any_ new or existing layers which have no text style applied. As in, the file is no longer able to "Create" new styles. You are however, able to update layers with existing styles.

## Example:
1. I opened an existing file to expand the text styles available.
2. I duplicated a list of layers with type styles applied to them. Adjusted the type, then detached the layer style.
3. I tried to use the plugin to create new styles, but the plugin appeared to do nothing. (no feedback other than the menu flashing) Fig. 1 below*

Figure 1: Selecting text laters and attempting to create from both the menu and the hotkey yielded no results.

## Troubleshooting/Pinning down the issue:
1. I copied the text from this file some with styles applied, the rest with the text styles detached (e.g. H1 and H2 are text styles, H3–H6 are just text layers and named in order to be generated into styles properly.)
2. Used the plugin. No issues. The layers with text styles applied that I copied in that had just "updated" or "didn't update since there was no change", while it created the other 64 instances. (Worked normally).

## Quick Fix / Alternate Path
I found by copying the detached style layers (properly named), and pasting them in a new file—I was able to generate the styles there. Following that I then copy/pasted them back into the origin file and the styles transferred. So this may mean I have a Sketch or file corruption issue in some way, but I'm not certain.

Hope this info is helpful.
