To make a clear understanding, its likely that some has watched youtubers playing the latest version from Patreon. Or that they got the version from a pirated site.
There is also a possibility that those people dont know/ cant get to their Discord server to ask about the version (Tho you have to be linked with a Patreon account to Discord, and have at least tier 3 or above)
My advice is to not download any games outside of Itch.io, since people cant understand that those games outside of itch.io is not the public version, and are more so prone to virus and hacking your account. Plus if you so wanted to ask on Discord about problems related to the version that isnt the free public version, you are very much going to be suspected to be a pirate, and therefor likely banned from that server.
