Hi Axel,
welcome in our small developer forum. 😃
Unfortunately, it's not the right place to discuss issues with MAXON Labs plugins. This forum is really focused on discussing development related topics with 3rd party developers. The comment you posted on MAXON Labs directly already was the right approach.
The thing with MAXON Labs is, that these are all side projects of our developers, often done in spare time. As the page states, MAXON does not promise any support or future maintenance. With that said, usually our developers provide support nevertheless, just because the want these projects top work ok. But then it also heavily depends on their current workload. I made the developer aware of the issue and it can be reproduced (which is always the first step to a fix), but I can't make any promises when he might find the time to look into it.
Cheers,
Andreas
