Now with OS 1.30B out, I mentioned this issue in the Syntakt Bugs thread here: SYNTAKT Bugs Thread - #570 by ThomasJ
It is basically the only remaining issue that we haven’t been able to reproduce yet, so are hoping to nail it down in the future. If @BRUTE still has this issue and it can be reproduced we would be happy to take a closer look, so please add a support ticket if so.
