Tried to update and it didn't work. It says it updated, but then if I click "manage" in itch app, it says it needs to install still. Clicking "install" gives a rather lengthy encrypted error message. Then, it reverts back to saying it needs an update. Looked into it further, it is not allowing me to install the non-4K version for PC. Even clicking on the non-4K download via the downloads section sends me to the install screen for the 4K one.
Sorry to hear, I've deactivated the 4k version for now. Hopefully this will fix the issue. I've used the butler app to upload the versions this time. I would expect it to focus on them first though.
Edit: found the issue, the window/Linux file didn't get set as win/linx after the upload. Should be fixed now! Thanks for letting me know :)
