when I tried it, it stopped any of the buttons in the stock and blizzy toolbars from loading in the VAB for me. I removed just this mod and the buttons all showed up again.
In a heavily modded setup. Can't reproduce, but there is an exception in the log :
NullReferenceException: Object reference not set to an instance of an object
ConfigNode.CopyToRecursive (.ConfigNode node, Boolean overwrite)
ConfigNode.CopyToRecursive (.ConfigNode node, Boolean overwrite)
ConfigNode.CopyToRecursive (.ConfigNode node, Boolean overwrite)
ConfigNode.CreateCopy ()
GameDatabase.GetConfigNode (System.String url)
UpgradesUIExtensions.PatchEditorTooltip.Start ()
I fear the exception is wreaking havoc in the GameDatabase, this is very bad and most probably the cause of toolbar icons being unable to load.
