I have not ruled out operator error, and am posting here in the hopes that someone can tell me the error of my ways.
Worked great the first time per the instructions I receive from the nice Boscoyo group. I inserted a Boyosco snowflake in xlights per their instructions (using the "Create New Download" tab, but did not have time to follow through so I deleted the model from my layout till I had more time to work on it.
I came back later to insert it again using the same "Create New Download" process, but am unable to insert the same model. When I try to insert it again, I get an error that reads: “Failure loading custom model file.”, and OK is the only option. That is followed by the error details “XML parsing error: 'duplicate attribute’ at line 2 16:52:01”.
