I have not done any updates in the past 24 hours and this only started during the last maintenance. Basically during any part of the code that executes a cloning or destroy of a BillboardGui (used for the players nametags, etc) will now return this error:
To make sure it was not something I did I went into a test server and pushed back to about 1 week ago and found that the exact same thing occurred. Not sure how this happened but I’d like it to be resolved as quickly as possible. Thanks.
So I looked into the problem more and apparently because the name of my BillboardGui was “Tags” it has caused this problem. Changing the name to “NameTags” has fixed this. Rather odd that this would appear now though I’m assuming its due to something they in the update today with the same name.
The issue is caused by a new unscriptable property I added to Instance in support of the upcoming instance tagging feature. I am going to fix this by preventing unscriptable properties from being considered in property lookups, and hopefully get that fix out asap, but it will be at least a week until that’s out.
