Not seen this error before

I often create my own VST3 plug-ins in Blue Cat Audio’s Plug’n’Script. I’ve never had a problem until today. Then…


Any ideas?

I may have answered my own question, though it still seems odd. I have created a few versions of this plug-in and it seems to be something to do with having re-used the name. I re-named a new build and it loads fine.

Is there a way I can avoid this problem (without having to re-name) for the future?
