So far, everything looked alright. Tonight I had one incident that I can’t quite put my finger on it: One of my contacts just lost their groups. Here’s the diff (anonymized):
diff --git a/55cd82aa-5d0d-444e-b414-3905d2193d42.vcf b/55cd82aa-5d0d-444e-b414-3905d2193d42.vcf

So, instead of the categories, suddenly there’s a line just saying
<space>1 (1 with leading space). This is not forum formatting, or the leading space of the diff format, this is actually in the vcard.
I did have other syncs that same day which still have their catetegories. They also have the
<space>1 extra line.
Again, not sure if this is related, but I thought I’d mention it.
