It wouldn't be tf2tags without set issues.
For the time being try to avoid sets larger than say 10 items. Something is essentially causing the data to get cut off making set submissions fail when the total data is above a certain length.
I suggest you plan your sets in notepad so you have a spare copy if they fail to go through for later. More info as it comes.
Oh I also added some missing paints for the new robo-hats. They're not all up on the wiki yet, so there's still more. If you come across any other hats that still have placeholder painted images leave a comment on my steam profile
