So, I have been adding some more types of glass panes in a upcoming update for QuestTest.
I added nether glass panes, basically copying the registration of regular glass panes, changed the name, description, and textures, and tested.
After placing some nether panes, I placed a regular glass pane directly next to the nether glass pane. The nether glass pane was changed into regular glass pane, of the same "form", that is, if it was connected to some other nether panes, it stayed connected, while connecting to the placed glass pane. When I dug the replaced pane, it converted the nether panes it touched into regular glass panes, like an infection. I checked to make sure it was not just converting images, but it was changing the node. This did not happen in reverse (nether panes placed next to regular panes turning the regular into nether panes), nor between regular panes and Iron bars.
There were no errors in the debug.

here is my code:

could someone please either tell me what is going and how to fix it, or, if the error is in Xpanes, fix Xpanes (and post the repaired version somewhere).
Thank you.

It seems that your naming is too specific. The name "pane_" is used in the node definition of the xpanes. I suppose the functions of placing, digging and updating do not check if there is a number or a string after the underscore of "pane_", so it just replaces your node with the pane node from xpanes. Just rename your node e.g. to "netherpane" to fix it and avoid naming that starts with "pane_" or "bar_" which is already used.

thanks. It works. And thanks for the quick reply.
