We're aware (and are working on a fix) for a current issue in the livery UI, which we're aware has impacted several players' abilities to select custom liveries since yesterday's (Tuesday 2nd's) patch. We appreciate this isn't ideal, but it is a UI issue, rather than any of your saved liveries being deleted. We're working on a fix, and will release it after we've been able to test it thoroughly. Thanks for your patience, apologies for any inconvenience caused, and we'll let you know when the fix has been implemented. This is now fixed. Thank you for your patience!
