Build 3186 (Experimental) bug

Hi all,
Anyone else see this. The new build puts this up when I try to replace the plugin when it already existed before the new build was installed, it will not complete the change of the plugin and reverts to the original. If I create a new plugin in the same song I can then replace it.

Thanks

Thanks @dave_dore,

Found it, fixed it. (Fix will be in next build)
