My PC is running the latest version of Windows, and I work on Inkarnate maps using Brave as my browser. I started working on some maps a year or so ago, before stopping until today. I resubscribed to the more expensive plan to try out the new features in 2.0, but some of the older maps started having serious problems. They wouldn't load, prompting me to save a backup and restore them, and when they did load, some details were missing. Even after reloading the saved backup, the page would automatically reload while I was working, erasing some of my work, particularly those with the Brush Tool. It wasn't even replaced with the previous version of the texture, but was completely erased, repeatedly, making it virtually impossible to continue working. If the problem persists, I'll be forced to ask for a refund, as I won't be able to use it.
