Not a crash, just that I keep getting log spam with this statement.
"[Render thread/INFO] [Create Deco/]: placard tooltip was null"

Keep it up the good work :)

P.S. Please use Ctrl-F for to find the statement. The log is quite extensive.

This is a known issue that's been around for a while, I put it in as a debugging help and never removed it. Thanks for the report though!
