Sounds weird!?
We have had problems with people leaving fake predatory links and saying "New update!" we have reported them to Itch and that might have resulted in harder moderation in our comment section - but i don’t understand why your comment was removed.
To answer you question:
No it is not intentional that the ticket symbols change if you start scratching manually and then, before finishing, switch to the scratch bot. It was a result of how the tickets were generated. We have fixed the issue and it will be in the next update =D
