@mannyv Hi, sorry about the spamming, I’ve found my misunderstanding about the code. Normally tuple spaces are handled by flattening, but I disabled my preprocessor because of this previous issue I had. Therefore the padding couldn’t be done correctly. The reproduction script is likely also due to the previous issue I had that hadn’t been fixed yet.
So I think a solution to this should be instead of disabling the preprocessor, I should write a custom pre-processor that only flattens tuple into vectors? Is this correct?
