Lua Panic! Something went horribly wrong!

"attempt to index a number value"

I wasnt sure weather this would be a lua question or not so i decided to post here first. If anyone has any suggestions or help please let me know.

I have this error, too and I do not know how to fix it. I have it since the update.
